Unformatted text preview: down. Hyper Chem is a molecular visualization and calculation package. Do you know how you wished that you could see things like molecules and orbital so they were not so abstract? Well, this is what Hype them does. At its simplest level, Hyper Chem allows you to visualize molecules in three dimensions, including zooming in or out, or even rotating the molecule so you can see it from different perspectives. Hyper Chem allows you to import molecular structures or build your own, and change the way it looks, but it can do much more. In addition to simple visualization, Hype Chem is a powerful tool for calculating the properties of molecules. At this point, we will be using these tools blindly; that is, l will not be giving you a lot of details on how it is working, but we can still get a lot out of it. Some of these are more or less automatic. For example, when you build your own molecule, Hyper Chem automatically calculates the most likely bond angles and lengths. In addition, Hyper Chem can do things like simulate molecular motion, or calculate and display electron orbitals. Using these tools help make chemistry feel less abstract. Starting Hyper Chem I will assume you hove already bought your copy of Hyper Chem If not, it is available for download at http://www.hyper.com (go to the student version) and can be downloaded and used for free for 30 days. However, yow will want to purchase the progr am for this course. In this introduction, I will show you the basics of Hyper Chem, but more specific instructions will be included with those experiments that utilize it. Basic Hyper Chem Building Tools If you have purchased and installed Hyper Chem, it should be in your program files. Just start it up normally. By default, it starts with a black screen, which can be intimidating, but don’t let it be.

Dakota State University Page 24 of 232 Using HyperChem General Chemistry I and II Lab Manual To build a molecule from scratch (say, for example, isopropanal), begin by double clicking on the draw key. This will open up a periodic chart for you (to the best of my knowledge, this is the ONLY way to get the periodic chart to open). Notice that every element is here (as is on ANY periodic chart). To build our molecule, select carbon (C), and “place” a carbon somewhere in the black area. Notice that you might have to click twice to get the carbon to show (it will appear as a small blue circle); this is because when you click on the periodic chart, that becomes the active window. The first time you click on the black background, it makes the Hyper Chem window the active screen, so the second click is required to place the carbon.
