Abstract

The infrared spectral absorptance of HCl was measured experimentally at temperatures ranging from room temperature to 1200°K. The measured spectral absorptance was compared to that calculated from band model theories and from a simple isolated line model. Agreement between calculation and theory was good. The band model calculation fit the data best at high temperature; at low temperature, where the band model theory was less successful, the isolated line theory gave an excellent fit.
