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, whi...

| Zusammenfassung: | 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. |
