✦ Synopsis

Using the observed Raman fundamental frequencies of GeHCb and GeHBra the potential constants on the basis of Wilson's group theoretical method and the thermodynamic properties upto a rigid rotator, harmonic oscillator approximation were calculated.

The Raman spectra of various Germanium compounds have been studied by Dalwaulle(l) and the fundamental frequenciesoccur at 181 cm-1 (A& 409 cm-l (AI), 2159 cm-l (AI), 149 cm-1 (E), 438 cm-1 (E) and 699 cm-l (E) for GeHCls and 128 cm-1 (AI), 273 cm-1 (Al), 21 16 cm-1 (AI), 95 cm-l (E), 325 cm-l (E) and 674 cm-1 (E) for GeHBrs. The molecular parameters for GeHCl3 given by Venkateswarlu et a1 (2) are as follows : Ge -H = 1.55 AO, Ge -C1= 2.1 139 AO, C1-c e -
