The meansquare 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 rootmeansquare amplitudes of interatomic distances are calculated from these force constants and fundamental frequencies. According to the magnitudes of rootmeansquare 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.
