Slide Number 5

System Requirement

To record this tutorial, I am using
  • Ubuntu OS version. 12.04
  • Jmol version 12.2.2 and
  • Java version 7
Cursor on Jmol panel.

Cursor on 2-chloro-1-propanol molecule.

I have opened a new Jmol window with a model of 2-chloro-1-propanol on the panel.
We can rotate and zoom the model, to get a better perspective of the structure.
Cursor on 2-chloro-1-propanol molecule


Click on“Rotate molecule” icon on the tool bar.

To rotate the model, click on the “Rotate molecule” icon on the tool bar.


Click on the molecule. Click on the model.

Observe that the cursor changes to a hand icon.

Drag the mouse. Holding down the mouse button, drag the mouse on the Jmol panel.


You can see the model is rotating.

Place the cursor on the model.


Move the mouse wheel up and down.

To zoom-in and zoom-out, place the cursor on the panel.


Move the mouse wheel upwards to zoom-out, downwards to zoom-in.

Assignment


As an assignment,
  • Create a model of 2-chloro-3-Iodo-pentane.
  • Explore the “Spin” option in the Pop-up menu.
  • Change the direction of spin to “Z” axis and rate of spin to “40”.
  • Hint: Use Set Z Rate option

Your completed assignment should look as follows.

Cursor on the panel Let us now learn about the View menu.
Click on the “View” icon. View” menu on the menu bar, has options to view the model from various angles.
Click on the 'View' menu. Click on the 'View' menu.
Scroll down the menu. Scroll down the menu and choose from the various options provided.
Click on “Top” For example, I will choose “Top” view.

Click on the 'Top' option.

Cursor on the panel The image on the screen shows how the molecule looks from the top.
Cursor on the panel We can save this view as an image in various file formats.
Click on the “Save current view as an image” icon. Click on the “Save current view as an image” icon.
Cursor on the dialog box. A “Save” dialog box appears.
Scroll down “Image type” To select the file format, scroll down the options on the “Image Type”.
Click on JPEG I will select JPEG format.
Cursor on the dialog box. Open the folder in which you want the file to be saved.
Select Desktop. I want it on Desktop.

Select Desktop and click on Open button.

Cursor on the “file name” In the File Name text-box, type “2-chloro-1-propanol”
Click on jpg Go to “Files of Type” and select jpg.
Click on Save button. Click on Save button.
Cursor on the Jmol panel The image will now be saved in JPEG format on the Desktop.

<PAUSE>

Cursor on the Jmol panel. The style of display of molecular model can be modified in various ways.


Size and color of atoms and bonds in this molecule can be changed, if required.

Scroll down the Pop-up-menu We have an option to modify all the atoms in the molecule or a select set.
Cursor on the Jmol panel. The default display of the model on the panel is of ball and stick.
Open Pop-up-menu To change the display into “CPK Space fill”, open the Pop-up-menu.
Go to “Select” and click “All” . Go to “Select” and click on All to modify the whole molecule.
Open the Pop-up-menu.

Scroll down.

Open the Pop-up-menu again.

Scroll down to 'Style' and select 'Scheme' from the sub-menu.

Select first “Style” go to “Scheme” >>click on “CPK Spacefill”. And click on CPK Spacefill option.
Cursor on the panel The model on the screen is converted to CPK Spacefill model.
Let us now convert it back to ball and stick model.
Cursor on the panel.

Open Pop-up-menu, >>“Select” click on “All”.

Let's follow the same steps as before.
Open the Pop-up-menu>> “style”, >>“scheme”>> click on “ball and stick”. Open the Pop-up-menu.

Scroll down to “Style”, select Scheme and click on Ball and Stick option.

Cursor on the model. The model is now converted to ball and stick style display.
Cursor on the model. The size of the bonds can be changed using Pop-up menu, as well as Display menu on the menu bar.

Scroll down the display menu.

Click on the Display menu and select Bond.


The sub-menu has options of bonds in different size diameter, in angstrom units.

Click on “0.01 A”. For example, I will select “0.1 Angstrom” and click on it.
Cursor on the panel. Note the change in the thickness of the bonds.
Cursor on the panel. We can also change the colour of atoms and bonds.
Cursor on 2-chloro-propanol I want to change the colour of all the Carbon atoms in the model, to yellow.
Right-click, go to “select”. To do this, open the Pop-up menu and go to Select.
Scroll down to “element” >> click on “carbon”. Scroll down to Element and click on C-carbon.
Right-click>>select “Color”, select Atoms.


Open the Pop-up menu again and select Color.


Then select Atoms and click on Yellow from the options.

Cursor on the panel We can display the image with “X,Y and Z” axes and within a bounding box.
Right-click on the panel, select “style”

scroll down the sub-menu and select “axes” .

Open the Pop-up menu and select Style.


Scroll down to Axes option.

Cursor on the sub-menu From the sub-menu select Pixel Width .
Click on 3 pixel. I will choose 3 px. as pixel width.
Cursor on the panel. We now have the model on screen with all the axes.
Right-click on the panel,>> select “Style” .

scroll down the sub-menu >> select “Boundbox” .

Click on “3 px”

To draw a bound box around the image, open the Pop-up-menu.


Scroll down to Style, and select Boundbox from the options.

Select Pixel width and click on the pixel width 3 px.

Cursor on the panel. On the screen we have the model of 2-chloro-1-propanol in Boundbox with Axes.


To view the Boundbox clearly, we may have to zoom-in or zoom out.

Cursor on the panel Save the image and exit the program.
