Rotational Line-Width Measurements on NO, HCl, and HBr

Abstract
Quantitative measurements of apparent rotational line half‐widths are described for NO, HCl, and HBr. Theoretical relations, which apply to vibration‐rotation bands with spectral lines of uniform half‐width and Lorentz contour, have been used to obtain apparent rotational half‐widths from experimental data for CO and for NO.
