Abstract
A 1-m length absorption cell has been designed for observation of ir absorption spectra of gases at high temperatures. The design allows use of windows of NaCl, KBr, etc., which have a tendency to cleave when subjected to temperature variations. The absorption spectrum of HCl37 at temperatures in excess of 800°C revealed more than twenty-five previously unobserved lines in the 1–0 band of this molecule. Some molecule constants of HCl37 have been evaluated. Usefulness of the cell in work connected with other molecular problems has been indicated.Keywords
