Abstract. An experiment suitable for first-year students is reported. In this activity, students use a molecular modeling program to compute infrared spectra for a series of molecules. From the data obtained, students generate a group frequency chart and use it to identify unknowns. This provides students with an introduction to vibrational spectroscopy and the use of molecular modeling.

Key Words:  Laboratories and Demonstrations; general chemistry; molecular modeling; infrared spectra
