Abstract: | An IR spectroscopic study has shown that GeH4 molecules are situated on one set of sites of C, symmetry in phase IV. The III–IV transition at 63 K is apparently a second-order phase transition. In phases II and III the molecules are on sites of C3v. or C3 symmetry. The II–III phase transition was observed at 67 K. In solid GeD4, phase transitions were observed at 68.5 and 77 K. In phases II and III the site symmetry is CI. The II–III phase transition in GeD4 is apparently second order. There is evidence that the ν1, vibration of GeD4 is IR active in the solid state. |
