Time
Narration
00:01 Welcome to this tutorial on Surfaces and Orbitals in Jmol Application.
00:07 In this tutorial, we will learn to:
00:10 * Create models of Alicyclic and Aromatic molecules.
00:14 * Display different surfaces of molecules.
00:18 * Display Atomic and Molecular orbitals.
00:22 To follow this tutorial, you should know how to create and edit molecular models in Jmol Application.
00:29 If not, watch the relevant tutorials available at our website.
00:35 To record this tutorial, I am using:
00:38 * Ubuntu OS version. 12.04
00:42 * Jmol version 12.2.2 and
00:45 * Java (JRE) version 7.
00:48 I have opened a new Jmol application window.
00:52 Let us first create a model of cyclohexane.
00:56 Click on modelkit menu.
00:59 A model of methane appears on the panel.
01:03 To create cyclohexane, we have to make a hydrocarbon chain of six carbon atoms.
01:09 We will substitute the hydrogen in the model with a methyl group.
01:13 To do so, we will place the cursor on the hydrogen and click on it.
01:18 This is a model of ethane on screen.
01:21 Repeat this step another 2 times and replace one hydrogen at a time with a methyl group.
01:28 Click on the hydrogens in such a way that the structure forms a circle.
01:33 Now, rotate the structure on screen using the Rotate molecule tool.
01:38 This is the structure of butane on the panel.
01:41 Click on the modelkit menu.
01:45 Click on hydrogen on any of the carbon atoms present at the end of the chain.
01:52 Here is a model of pentane on the panel.
01:55 Click on one of the hydrogens, that is close to the end of the carbon chain.
02:00 A model of cyclohexane is created on the panel.
02:04 Use minimize option in the modelkit menu to optimize the structure.
02:09 The model of Cyclohexane is now in its most stable “chairconformation.
02:15 Alternately, we can also use Drag to bond option in modelkit menu to create cyclic structures.
02:24 I will use a model of pentane to demonstrate this feature.
02:29 This is a model of pentane on the panel.
02:32 To convert this into cyclopentane, select Drag to bond option from the modelkit menu.
02:40 Place the cursor on the carbon present at one end of the chain.
02:45 Hold down the mouse button.
02:47 Without releasing the mouse button, bring the cursor to the carbon present at the other end of the chain.
02:54 Now release the mouse button.
02:57 We have a model of cyclopentane on the panel.
03:01 Now Let us go back to the Jmol panel with the model of cyclohexane.
03:06 Let us now convert cyclohexane to a benzene ring.
03:10 We have to introduce double-bonds at alternate positions in the cyclohexane ring.
03:16 Open the modelkit menu.
03:19 Place the cursor on the bond between any two carbon atoms and click on it.
03:25 We now have cyclohexene on the panel.
03:29 Next, we need to introduce two more double-bonds in the structure to convert it to benzene.
03:36 Click on the bond between the next two alternate carbon atoms.
03:41 We have a model of benzene on the panel.
03:44 Do the energy minimization to get a stable conformation.
03:49 Surface topology of the molecules can be displayed by using Jmol Application.
03:56 To view different surfaces, open the pop-up menu.
04:01 Ensure that the modelkit menu is closed, if it is open.
04:06 Now, right-click on the panel to open the Pop-up menu.
04:10 Scroll down and select "Surfaces".
04:14 A sub-menu opens with many options-
04:18 Dot Surface,
04:20 van der Waal's,
04:21 and some others.
04:23 For demonstration purpose, I will select Molecular surface.
04:28 The model of Benzene is displayed with a molecular surface.
04:33 Let us change it to another surface, say, Dot Surface.
04:38 So, open the Pop-up menu again and choose Dot Surface.
04:44 We can also make the surfaces opaque or translucent.
04:48 To do so, open the Pop-up menu.
04:52 Scroll down to Surfaces and select Make Opaque options.
04:59 Observe that the benzene model has become opaque.
05:03 To turn off the surface option- open the Pop-up menu, choose Surfaces,
05:10 scroll down to Off and click on it.
05:15 Now, we have a model of benzene without any surfaces.
05:20 Jmol can display atomic and molecular orbitals of molecules.
05:25 Atomic orbitals can be displayed on screen by writing commands on the console.
05:32 Open a new Jmol window by clicking on File and New.
05:37 Now, open the console window by clicking on File and then on Console.
05:43 The console window opens on the screen.
05:47 I am using KMag Screen magnifier to magnify the console window.
05:53 The command line for atomic orbitals starts with isosurface phase atomicorbital.
06:00 At the ($) dollar prompt, type: isosurface phase atomicorbital.
06:06 This is followed by quantum numbers n. l and m that are specific for each atomic orbital.
06:14 To display 's' orbital, type: 2 0 0
06:20 The Numbers 2, 0, 0 represent n, l and m quantum numbers respectively.
06:27 Press Enter key to execute the command.
06:31 We have s-orbital displayed on the panel.
06:35 Here are few more examples of atomic orbitals and the corresponding script commands.
06:41 The command line is same for all atomic orbitals.
06:45 To display the previous command on the console, press up-arrow key on the keyboard.
06:51 Edit n, l and m quantum numbers to 2 1 1.
06:58 Press Enter key and see the 'px' orbital on the Jmol panel.
07:05 Press up-arrow key again and edit n, l and m to 3 2 and -1.
07:13 Press Enter key and see the 'dxy' orbital on the Jmol panel.
07:19 We can also save these images in different file formats like jpg, png or pdf.
07:27 Here is a list of commands for all atomic orbitals (s, p, d, and f).
07:35 Shown on this slide are models of atomic orbitals.
07:40 They were created with the help of script commands written on the console.
07:45 Here, I have opened a new Jmol panel and console to show how to display molecular orbitals.
07:53 Hybridized molecular orbitals such as sp3, sp2 and sp can be displayed using Jmol.
08:02 We have a model of methane on the panel.
08:06 Methane has molecular orbitals of the type sp3.
08:11 Linear Combination of Atomic Orbitals i.e. LCAO method is used to create molecular orbitals.
08:21 So, the command line starts with 'lcaocartoon', followed by create and the name of the orbital.
08:30 At the dollar prompt, type: lcaocartoon create sp3
08:36 press Enter.
08:38 Observe the model of methane with sp3 hybridized molecular orbitals.
08:45 To display sp2 hybridized molecular orbitals, we will take ethene as an example.
08:52 This is a molecule of ethene on the panel.
08:56 Ethene molecule has three sp2 hybridized molecular orbitals. They are named sp2a, sp2b and sp2c.
09:08 At the dollar prompt, type: lcaocartoon create sp2a , press Enter.
09:17 Observe the sp2 orbital on the ethene model on the panel.
09:22 Press up-arrow key and change sp2a to sp2b, press Enter.
09:31 Again, press up-arrow key and change sp2b to sp2c, press Enter.
09:41 Finally for the pi bond, edit the name of the orbital as pz.
09:48 On the panel, we have ethene molecule with all the molecular orbitals.
09:55 This slide shows examples of few other molecules with molecular orbitals.
10:01 Explore the website for Jmol Script documentation for more information.
10:08 Let's summarize.
10:10 In this tutorial, we have learnt to:
10:12 * Create a model of cyclohexane and cyclopentane
