Measurements of line intensities and half-widths in the 10-μm bands of [formula omitted

Abstract

We present measurements of the absolute intensities and collision-broadened half-widths of spectral lines in the 10 μm bands of 14 NH 3 . H 2-broadened, N 2-broadened, and O 2-broadened half-widths of lines aP(6,5)– aR(8,8) have been measured at 200, 255, and 296 K . Air-broadened and self-broadened half-widths are presented at 296 K . The variation of linewidths with the temperature and with the rotational quantum numbers J and K is examined. A polynomial function of m and K which fits the observed linewidths accurately is presented.
