00:00 Khublei iaphi baroh.
00:01 Nga pdiang sngewbha iaphi sha ka jinghikai halor ka Orbital Overlap haka GChemPaint.
00:06 Hakane ka jinghikai,ngin ia pule -
00:08 shaphang kiba bunjait ki types jong ki orbitals
00:11 Rotation bad resize ia ki orbitals
00:14 Types jong ki orbital overlaps.
00:17 Hangne nga pyndonkam da ka Ubuntu Linux OS version 12.04,
00:21 Ka GChemPaint version 0.12.10.
00:26 Ban bud iakane ka jinghikai phi dei ban don ki jingtip shaphang ka,
00:31 GChemPaint chemical structure editor.
00:34 Lada em,ia ki jinghikai ba iadei ,sngewbha leit sha ka website jong ngi.
00:38 Nyngkong to ngin iapeit shaphang kaei kata ka atomic orbital kadei .
00:42 Ka atomic orbital kadei ka mathematical function.
00:46 Ka batai ia ka jinglong kumba iaid ka um jong ki electron ha u atom.
00:52 Ka orbital kadei ka bynta jong ka jaka ba lait daka maximum probability ban wad ia u electron.
00:58 Kane kadei ka 's' orbital.
01:00 Kadon ia ka dur ba pyllun(spherical).
01:03 Hangne kadei ka 'p' orbitals ha ki axes bapher bapher.

09:04 Ka batai pynlyngkot ia ka Spoken Tutorial project.
09:07 Lada phim don ia ka bandwidth ba biang, phi lah ban download bad sa peit pat.
09:12 Ka Spoken Tutorial Project Team: ka pynlong ia ki workshops da kaba pyndonkam da ki spoken tutorials.
09:16 Ai syrnod ia kito kiba pyndep iaka online test.
09:20 Iaki jingtip kiba kham bniah, sngewbha thoh sha ka contact@spoken-tutorial.org.
09:27 Ka Spoken Tutorial Project ka dei shi bynta jong ka Talk to a Teacher Project.
09:31 La kyrshan ia ka da ka National Mission on Education lyngba ka ICT, MHRD, jong ka sorkar India.
09:37 Ia ki jingtip ba kham bun halor kane ka mission kidon ha kane link http://spoken-tutorial.org/NMEICT-Intro
09:43 Ia ki dur la ai da ka Arathi.
09:45 La pynkylla ia kane ka script da i Strong bad la dubbed ia kane ka script da u Thawlad Miki. Khublei Shibun iaka jingiashim bynta jong phi.
