Force constants were evaluated for ruthenium hexafluoride, rhodium hexafluoride, tungsten hexachloride and tungsten hexabromide, making use of the Wilson's group theoretical method and the redundancy conditions. The mean amplitudes of vibration for these molecules were computed for the temperatures T = 0 and 298 deg K. The inactive frequency under the F/sub 2/, symmetry species for ruthenium hexafluoride was estimated to be 188 cm/sup -1/ from the force constants. The Ru--F and Rh--F interbond distances were also estimated employing these force constants and Badger's empirical relation. The molar thermodynamic functions for the ruthenium hexafluoride and rhodium hexafluoride molecules were calculated with the assumption of a rigid rotator, harmonic oscillator model for the temperature range 50 to 2000 deg K.
