The mean-square amplitudes of interatomic distances in hexafluoride molecules
Abstract
Possible values of force constants are estimated by using fundamental frequencies and a general quadratic potential function for hexafluorides of S, Se, Te, Mo, W, Re, Os, Ir, Pt, U, Np, and Pu. The root-mean-square amplitudes of interatomic distances are calculated from these force constants and fundamental frequencies. According to the magnitudes of root-mean-square amplitudes hexafluoride molecules are classified into the following groups, (1) SF 6, SeF 6, and TeF 6 containing np electrons, (2) molecules from MoF 6 to PtF 6 containing 4 d or 5 d electrons, and (3) UF 6, NpF 6, and PuF 6 containing 5 f electrons.
