摘要

Raman spectra of schmitterite measured at 298 and 77 K are presented and discussed in detail and in part in comparison with published IR spectrum of synthetic schmitterite. U-O bond lengths in uranyls, calculated with the empirical relations RU-O = f[v(1)(UO2)(2+)] angstrom and RU-O = f[v(3)(UO2)(2+)] angstrom, are close to those inferred from the X-ray single crystal structure of synthetic schmitterite and agree also with the data for other natural and synthetic uranyl tellurites.
