Measurements of line intensities and half-widths in the 10-μm bands of 14NH3

We present measurements of the absolute intensities and collision-broadened half-widths of spectral lines in the 10 μm bands of 14NH3. H2-broadened, N2-broadened, and O2-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
