摘要: Abstract The lattice resonances of crystalline solids, which lie in the far infra-red, give rise to broad absorption lines. High resolution is not essential for observation such A simple f /2 spectrometer with medium has been constructed this consideration mind. One spectral octave can be scanned fifteen minutes resolutions range 2–6 cm −1 and an accuracy ±2–3 per cent on transmission reflection measurements. This facilitates rapid measurement resonance frequencies which, conjunction Raman near infra-red studies, will make thorough examinations vibrations possible.
