Unitedhyphen;Atom Approximation Applied to Argonlike Molecules. II. PH2minus;, PH3, and PH4+

摘要

The unitedhyphen;atom treatment has been applied to the systems PH2minus;, PH3, and PH4+. For PH3and PH4+, satisfactory values are obtained for the total molecular energy and ``breathing'' force constants when compared with experiment. The model gives theoretical bond lengths which are in good agreement with the observed values. Coherent xhyphen;ray scattering factors are presented for PH3and PH4+along with a discussion of the molar diamagnetic susceptibilities. The value of the proton affinity derived here for PH3is found to be in general agreement with the experimental results.Except for the considerable improvement in the protonhyphen;affinity calculation, the results obtained here are in keeping with the conclusions derived from our earlier work concerning the unitedhyphen;atom study of H2S.
