Assignment of torsion and low frequency bending vibrations of secondary chlorides
Abstract
Far infrared and Raman spectra of 2-chloropropane, 2-chlorobutane and dl- and meso-2,4-dichloropentane have been analyzed in order to assign the torsional force constants in the valence force field for secondary chlorides. Band assignments have been based on experimental data as well as preliminary normal vibration calculations. With incorporation of torsional force constants, and a global refinement of the force field, the observed low frequency bands of the above molecules, as well as those of 3-chloropentane, are very well accounted for.
