✦ Synopsis

The n 4 band of NH / 4 was observed with a diode laser spectrometer. The molecular ions were generated in a watercooled, concentration-modulated, hollow-cathode discharge of hydrogen and ammonia gases. Forty lines were measured and assigned to NH / 4 . These new data were combined with 56 previously published n 4 transitions, and 24 ground state combination differences from the n 3 band. The combined data set was fit with a fourth-order spherical rotor Hamiltonian to provide improved molecular parameters for the £ 4 Å 1 and ground states.

H 2 -broadening coefficients have been measured for 66 rovibrational lines of NH 3 at room temperature in the P P and R P branches of the ν 4 band in the range 1470-1600 cm -1 , using a high-resolution Fourier transform spectrometer. The collisional widths are obtained by fitting Voigt profiles to t
