Abstract. An integrated experiment on vibrational spectroscopy is presented. The experiment utilizes the ir and Raman spectra of a series of halomethanes to illustrate a number of techniques and concepts. Application of symmetry concepts, the uncoupled oscillator approximation, and molecular modeling are all employed to interpret the experimental data obtained. The experiment uses readily available apparatus and commercial software. Details for the assembly of a low cost Raman spectrometer are also provided.

Key Words: Laboratories and Demonstrations; Raman, infrared, vibrational spectroscopy, molecular modeling
