Title: High-resolution, temperature-dependent spectra of calcite
Abstract: High-resolution absorption spectra of the 2.0-3.5 μ region of a basal section of calcite are reported and analyzed. The resolution was accomplished with a 7500 ruling per inch "Merton-N.P.L."; replica grating mounted in place of the Littrow mirror of a Perkin-Elmer Model 13 Spectrometer, with a KBr prism left in place. A new explanation of some of the observed "splittings" in the 2.0-3.5 μ region is presented and tested. This analysis is similar to that suggested previously as an explanation of observed fine structure in the spectra of crystalline iodoform and brucite. Spectra of calcite were obtained from 78 to 873 K; the observed modifications in the spectra confirm the hypothesis of "librational interaction".
