Abstract

An experimental unit for recording the combined reflection-absorption spectra of low-temperature liquids was designed and manufactured and an algorithm for obtaining the extinction coefficient was developed. The manufactured experimental unit and the algorithm were tested by recording, for the first time, the absorption spectrum of liquefied CF4. The band parameters derived from the experimental data are compared with estimates available in the literature.
