Abstract:
Spectral transmittance measurements have been performed on N2-broadened lines of C2H2 in the 7.53 μm region at 153 and 200 K with a spectral resolution of 0.06 cm-1. The line widths have been determined as functions of temperature and rotational quantum number using line-by-line comparison of theoretical and experimental values of spectral transmittance.
