Crystalline sulfur dioxide: Crystal field splittings, absolute band intensities, and complex refractive indices derived from infra-red spectra
Abstract
The infra-red absorption spectra of thin crystalline films of sulfur dioxide at 90 K are reported in the 2700-450 cm -1 region. The observed multiplicity of the bands in the regions of fundamental modes is attributed to crystal field effects, including factor group and LO—TO splittings, and naturally present minor 34S, 36S and 18O substituted isotopic species. Complex refractive indices determined by an iterative Kramers—Kronig analysis of the extinction data, and absolute band strengths derived from them, are also reported in this region.
