Laser-Raman spectra have been measured for PH4C1, PIQBr and PH& Intense peaks in all the halide spectra are assigned to torsional (E ) oscillations and to the internal vibrations of the PI-I-ions. Barriers to PHZ rotation are calculated and lscussed in comparison with recent spectroscopic an structu

## Abstract Free energies of activation, Ξ”__G__, for the rotation of the phenyl group in the range of 46.06–63.25 kJ mol^βˆ’1^ were observed in some model β‐hydroxyphosphonates. These barriers were found to depend on the type of substituents at the phosphorus atom and on the substituents at the β‐pos
