| 00:01 | Pdiang sngewbha sha kane ka tutorial halor Symmetry and Point Groups haka Jmol. |
| 00:06 | Ha kane ka tutorial, ngin pule ban: |
| 00:08 | Dro lain, kata, axis lyngba ki atom ha u molecule. |
| 00:12 | Spin bad rotate ïa u molecule shilynter jong u axis. |
| 00:17 | Dro ïaka plane lyngba ki atoms ha u molecule. |
| 00:21 | Bad pyni ïaka jingbuh kyrdan jong ki point group. |
| 00:25 | Ban bud ïa kane ka tutorial, phi dei ban don ka jing tip ïaka undergraduate Chemistry bad tip bha shaphang ka rukom treikam naka Jmol window. |
| 00:35 | Lada em, peit ïa ki tutorial ba kum kane kiba don haka website jong ngi. |
| 00:39 | Ban record ïa kane ka tutorial, nga pyndonkam ka: |
| 00:42 | Ubuntu Operating System version 14.04 |
| 00:46 | Jmol version 12.2.32 |
| 00:50 | Java version 7 bad * Mozilla Firefox browser 35.0. |
| 00:57 | Bunsien, ki symmetry haki molecule la batai ha ki kyntien jong ki symmetry elements kum: |
| 01:03 | Axis jong ka symmetry |
| 01:05 | Plane jong ka symmetry Center jong ka symmetry ter ter. |
| 01:09 | Ngin pyndonkam ka Jmol ban display kine ki symmetry element ha u molecule. |
| 01:14 | To ngin sdang ïa kane ka tutorial dakaba dro u C3 rotational axis lyngba ki atom haka model jong u methane. |
| 01:22 | Nga la plie lypa ïaka Jmol window. |
| 01:25 | Click haka modelkit menu ban ïoh ïaka model ball and stick jong u methane haka panel. |
| 01:31 | Label ïaki atom ha u methane molecule dakaba pyndonkam ïaka Display menu ha u tool bar. |
| 01:37 | Click ha ka Display, hiar sha Label bad click ha u jingjied Number. |
| 01:43 | Baroh ki atom ha u methane molecule lah ai number. |
| 01:47 | Ngi donkam ban thoh ki command ha ka console ban dro ïaki laiñ bad planes lyngba ki atom. |
| 01:53 | Ban plie ïa ka Console, click haka File menu. |
| 01:57 | Hiar sha ka Console bad click haka. |
| 02:01 | Ka Console window ka plie haka screen. |
| 02:04 | Ngin pyndonkam ïa ka kyntien draw haka command line ban dro ïaki laiñ bad plane. |
| 02:10 | Ka jingtip ba bniah halor ka Jmol script commands ka don hakane ka website. |
| 02:15 | Plie ïaka website ha uno uno u browser. |
| 02:19 | Ka web-page ka plie ryngkat bad ka list jong ki keyword bala pyndonkam na bynta ban thoh ki script command haka Jmol. |
| 02:26 | Hiar shapoh bad click haka kyntien draw haka list. |
| 02:31 | KA page ka plie bad ki jingbatai bniah shaphang ka draw keyword. |
| 02:36 | KA rukom pynbeit kyntien ba kyllum na bynta ka draw command la ai ha khlieh jong ka page. |
| 02:42 | La pynbud ïa kane da ka thup jingtip ba ïadei bad ka jingpyndonkam ïaka keyword. |
| 02:47 | To ngin leit phai biang sha ka Jmol panel. |
| 02:51 | Nga pyndonkam ka Kmag screen magnifier ban pyni heh iaka console window. |
| 02:55 | Ban dro u laiñ u ba thew ïa u C3 rotational axis, |
| 02:59 | type ïa ka command bala ai harum ha u dollar prompt, ha ka console. |
| 03:04 | U command line u sdang da ka kyntien “draw”, bad la pynbud pat da ka object ID. |
| 03:10 | U Number 250 ha u command line u thew ïaka jingjrong jong u laiñ. |
| 03:15 | La bud pat ïa kane da ka jaka shong jong u laiñ. |
| 03:18 | Hapoh ki bracket, atom number equal to 1 bad atom number equal to 2. Ñion Enter. |
| 03:26 | Khmih thuh haka panel. U laiñ ba ïaid lyngba ki atom 1 bad 2 la dro ha u model jong u methane. |
| 03:33 | Une u laiñ u long mynta kum u axis naka bynta ban pynshad. |
| 03:37 | Ngi lah ban dro palat ïa u wei u laiñ ha ka model bala ai. |
| 03:41 | Ban dro u C2 rotational axis, type haka console ïaka command bala ai harum. |
| 03:47 | Ha kane ka command, ki number haki bracket ba khun ki kdew ïa ki Cartesian coordinates naka bynta u line |
| 03:54 | bala pynbud daka command ban batai ïaka rong jong u laiñ. Ñion Enter. |
| 03:59 | Mynta haka panel, ngi don u methane ryngkat uC2 bad C3 rotational axes. |
| 04:05 | Ban rotate ha shi lynter u line 1, kata u C3 axis, type ïaka command harum: |
| 04:12 | rotate $line1 60 (rotate space dollar line1 space 60). |
| 04:18 | U number 60 u pyni ïa ka degree jong ka rotation. Ñion Enter. |
| 04:24 | Khmih thuh ïaka jingshad shilynter u line1. |
| 04:27 | Ban spin ïa u molecule shilynter u line1, type ïa ka command harum: |
| 04:32 | "spin $line1 180 60" (spin space dollar line1 space 180 space 60). |
| 04:39 | U number 180 u thew ïaka degrees jong ka rotation bad u 60 u thew ïaka speed jong ka rotation. Ñion Enter. |
| 04:48 | Haka panel, ngi iohi ia u model methane uba spin shilynter u line1, kata u C3 axis. |
| 04:55 | Kum ka assignment-Dro u laiñ uba pynï ia u C3 axis of symmetry, ha u model jong u ethane |
| 05:02 | bad spin ïa u model shilynter jong u C3 axis. |
| 05:06 | Phai biang sha ka Jmol panel. |
| 05:08 | Ngi lah ruh ban dro ïaka plane kaba ïaid lyngba ka shi kynhuh jong ki atom ha u molecule. |
| 05:12 | ban leh kumta, nyngkong delete ïa u laiñ ha u model methane dakaba type ïaka command ba harum.
"draw off" (draw space off). Ñion Enter. |
| 05:24 | Ban dro ïaka reflection plane kaba ïaid lyngba ki atom 1, 2 bad 3 jong u methane molecule: |
| 05:31 | type ïaka command harum haka console. |
| 05:35 | U Number 300 haka command u kdew ïaka size jong ka plane. Ñion Enter. |
| 05:41 | Khmih thuh ïaka reflection plane kaba iaid lyngba ki atom 1, 2 bad 3 ha u methane molecule. |
| 05:49 | Ban dro ka reflection plane ba –ar lyngba ki atom 1, 4 bad 5: |
| 05:55 | Haka console, ñion u up-arrow key bad edit ïaka command kumba harum. |
| 06:01 | Edit plane1 sha plane2 bad atomno2 sha 4 bad atomno3 sha 5. |
| 06:12 | Bad ruh, ban pynkylla ïaka rong jong ka plane, type ïaka command harum: |
| 06:17 | "color $plane2 blue" (semicolon color space dollar plane2 space blue). Ñion Enter. |
| 06:24 | Haka panel, ngi iohi ar tylli ki reflection planes ha u methane molecule. |
| 06:29 | Pyndonkam ka Jmol, ngi lah ruh ban pyni ka jingphiah kyrdan u point group naka bynta u methane kum harum. |
| 06:36 | To ngin pynkhuid noh ïaki plane bala dro ha u methane molecule, haka panel. |
| 06:41 | Haka console, type: draw off (draw space off). ñion Enter. |
| 06:47 | Ban pyni ïa baroh ki symmetry element ba lah na bynta u methane: type ïa ka command harum haka console. |
| 06:54 | "draw pointgroup" (draw space pointgroup). Ñion Enter. |
| 06:59 | Ngi iohi ïaki symmetry elements jong u methane bala pyni haka panel. |
| 07:04 | Ban shem ïa ka jingbuh kyrdan point group na bynta u methane, type ïaka command harum:
"calculate pointgroup" (calculate space pointgroup). Ñion Enter. |
| 07:14 | Td,ka point group jong u methane molecule, la pyni haka console. |
| 07:20 | Sa kawei ka jingpyni nuksa ba bha tam na bynta ka jingpyni ïa ka point group ka dei allene. |
| 07:25 | Ngi lah ban dro ïaka structure jong u allene, haka panel, pyndonkam da ka modelkit menu. Lane, ngi lah ruh ban download ïaka structure jong u allene na ka chemical structure database. |
| 07:37 | Lada phi long connect sha ka internet - click haka File menu, hiar sha Get Mol bad type “allene” haka text-box. Click ha OK. |
| 07:48 | Ban pyni lut ia baroh ki possible symmetry elements na bynta u allene: |
| 07:52 | ñion u up-arrow key ha u dollar prompt, haka console, tad ynda phi ïoh ïa kane ka command: |
| 07:59 | draw pointgroup . ñion Enter. |
| 08:02 | Khmih thuh ïaka panel. Ngi iohi ïa baroh ki possible symmetry elements na bynta u allene. |
| 08:09 | Ban ioh ïa ka jingphiah kyrdan point group na bynta u allene - |
| 08:12 | Sa shisien, haka console, ñion ïa u up-arrow key tad ynda phi ioh ïaka command "calculate pointgroup". Ñion Enter. |
| 08:21 | Ka point group classification na bynta u allene, kata u D2d, la pyni haka Console. |
| 08:28 | Kumjuh ruh, phi lah ban download ki molecules jong ka jingkwah jong phi bad kheiñ ïaka point group jong ki. |
| 08:34 | To ngin Batai lyngkot. Ha kane ka tutorial, ngi la pule: |
| 08:38 | Ban dro ki laiñ, kata, C2 bad C3 rotational axes lyngba ki atom ha u methane molecule. |
| 08:45 | Spin bad rotate u molecule shilynter u axis. |
| 08:49 | Dro ka reflection plane lyngba ki atom ha u methane molecule. |
| 08:54 | Bad pyni ïa ka point group classification pyndonkam ki nuksa jong u methane bad allene. |
| 09:01 | Kum ka assignment- Dro ka reflection plane haka model jong u dichloromethane |
| 09:07 | bad wad ïa ka point group classification na bynta u ammonia bad benzene. |
| 09:12 | Kane ka video Ka batai lyngkot ïaka Spoken Tutorial project. |
| 09:15 | Lada phim don ka bandwidth ba biang, phi lah ban download bad peit ïaka. |
| 09:20 | Ngi pynlong workshop dakaba pyndonkam ki spoken tutorials bad ai certificates. sngewbha thoh sha ngi. |
| 09:27 | Ka spoken-tutorial project la bei tyngka daka National Mission on Education Lyngba ka ICT, MHRD, Sorkar India. |
| 09:33 | ïa kane ka script la pynkylla sha ka ktien Khasi da I Hezekiah Lyngdoh na Shillong. Khublei ba phi la ïasnohlang. |
