Paper Abstract

The far infrared spectra (350 to 35 cm-1) of a series of haloacetyl halides, CH2XCY0, in the vapor phase have been recorded at a resolution of 0.10 cm-1. The fundamental asymmetric torsional frequencies of the more stable trans (two halogen atoms oriented trans to one another) and high energy conformers have been observed and the asymmetric torsional potential functions governing internal rotation about the C-C bond have been determined. The conformation of the high energy rotamer is cis or gauche depending on the size and position of the substituted halogen. Ab initio calculations at the 3-21G, 3-21G* and 6-31G* basis set levels of the optimized geometries, potential surfaces and vibrational frequencies are used to support the conclusions made from the experimental results.
