If you want to get good vibrations - from your class, that is - take Vibrational Modes to your next lecture on molecular spectroscopy. Unlike textbook illustrations or chalkboard drawings, this simulation program lets your students see the vibrational motions of triatomic molecules. By viewing the motion and determining its symmetry, they can predict whether infrared absorption or Raman scattering will occur. Vibrational Modes features fast, time-accurate animation and adjustable parameters. Students can choose the atomic masses, molecular geometry, and force constants for the simulations and view the resulting modes individually or in linear combination. This promotes a clearer understanding of the relation between vibrational excitation and radiation. Vibrational Modes is appropriate for courses in molecular physics, chemical physics, or classical mechanics. 30 pp. System Requirements:
