ALP-vibro is a program for visualization/animation of molecular vibrations computed by Gaussian 98 and Gaussian 03 (www.gaussian.com). The maximum number of displayed atoms is 1000. You can rotate your molecule/ion in three dimensions to get a better view of the molecule and the vibration mode. It is a user-friendly program. The only required input from a user is the name of the Gaussian output file and the normal mode number you want to see. Download the program and the file sample (330 KB). You can also download the program at the Computational Chemistry List (CCL) server www.ccl.net.

Note that ALP-vibro is a "closed" project and no updates or modifications will be available.
