FAR INFRARED SPECTRA OF HALOGENATED PHENOLS. THE CALCULATION OF THE BARRIER HEIGHT OF THE HYDROXY GROUP FROM THE OBSERVED TORSIONAL VIBRATIONS.
Abstract
The far infrared spectra of ortho, meta and para fluoro-, chloro- and bromo-phenol have been observed. In several of these phenol molecules, for the first time the hot bands, i.e., higher transition 1 approaches limit of 2, 2 approaches limit of 3, could be resolved and both the V2 and V4 terms of the potential energy expression could be evaluated. The ratio of V4/V2 ranged from +0.026 to -0.017. Also, rotamers were observed in several of the meta halophenols. A set of Mathieu tables of very large s values used in the calculation of barrier height is given. (Author)
