Raman and Infra-Red Spectra of Î2-Quartz


THE Raman spectrum of Î2-quartz has been investigated by Narayanswami1. He finds that the frequency 466 of α-quartz appears at 452.5, whereas the frequencies 207, 356 and 1,082 of α-quartz are absent from the spectrum. He also finds frequencies at 97, 250, 395, 686, 792, 1,060 and 1,154 cm.â1, which correspond to the doubly degenerate frequencies 128, 265, 395–403, 695, 795–807, 1,063 and 1,159 of α-quartz. These facts find a ready explanation on group theoretical considerations, and in addition we can predict corresponding results for the infra-red spectrum.
