Abstract
The study of inorganic solid-state electronic and vibronic transitions at low temperatures, by a wide-range Fourier transform spectrometer, covering the range 150 to 47,500 cm−1, with a resolution between 0.5 and 2.0 cm−1, is described. The types of electronic transitions of molecular ions are given, and the link between calculation and experimental measurement is highlighted. Factors contributing to the linewidths in solid-state electronic absorption spectrometry are identified. The instrumental techniques for sample preparation and the recording of spectra at low temperature are described, together with parameters affecting the resolution, precision, and calibration of a Fourier transform instrument. Problems which may arise from sample heating, spectrum fringing, aliasing, and the operation of spectrum subtraction are discussed. Some applications of the Fourier transform spectrometer are presented.
