You will need MDL Chemscape Chime, which is a 3-D molecular modeling plug-in for your browser, in order
to view the molecules for this assignment. If you are working at
the Chemistry Learning Center, you should not have any problems
viewing the models. If for some reason you are having trouble because
the models are not automatically loading with the plug-in, click on the
"refresh" icon at the top of your screen. If that fails, reboot or move
to another computer.
If you are working outside of the
Chemistry Learning Center, the Chemscape Chime Plug-In for
Netscape or Internet Explorer browsers can be downloaded from
MDL
Information Systems Chemscape Chime.
Helpful Hints
The manipulation of molecules
in space using Chime 2.0 is controlled with the use of the mouse along
with holding down either the right or left mouse button and/or the shift
or control button on the keyboard. For more specific instructions on to
arrange molecules in space, click here to view the mouse controls help
page.
It may be easier to view the solid
molecule displayed in the sticks or ball & stick mode as opposed to the
default space-filling mode. To access the display and option menus, hold down
the right click button when you are in Chime.
If you are unsure of the identity of
the atoms in some of the models, use labels located in the Chime options
menu since some of the colors may be the same even for different
elements.
If Chime does not load properly,
click on "refresh" located with the browser icons. If an error prompt
appears, it may be necessary to reboot the computer, or move to another
PC.
When finished viewing, click on
"back" located with the browser icons to return to this page.
Please spend a few minutes to familiarize yourself with the software before you start on the assignment.
Solid State Crystal Structures
The computers in the Chemistry Learning Center already have Chime installed.
To display and rotate the molecules, right click, and select either
Display or Rotation.
For additional help with the mouse controls, open the menu page
by holding down the mouse button in the Chime display.
