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
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 23 of 232 Using HyperChem General Chemistry I and II Lab Manual The most important keys are on the bar; although hovering your mouse above them will
bring up an explanation, you will find that you quickly learn what they are and their function. 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. Dakota State University Page 25 of 232 Using HyperChem General Chemistry I and II Lab Manual Now, we want to attach a...
