Low temperature hydrogen broadened linewidths of ammonia in the (0,1,0,0)?(0,0,0,0) band at 200 K
Abstract:
Fourier transform spectra of the (0,1,0,0)?(0,0,0,0) band of ammonia have been measured for values of the hydrogen broadened linewidth parameters at a temperature of 200 K. The halfwidths for >200 lines have been determined with an average RMS of 5% in the interval between 750 and 1250 cm(-1). No measurements of the widths in the (s)R branch, and only 12 widths in the (s)Q branch, were obtained because of severe lending of the J-K manifolds. The broadening coefficients vary between 0.06 and 0.14 cm(-1)/atm. for (J,K) < (12,12).
