## Abstract The selfβbroadening of the __Q__βbranch vibrationβrotational lines in the CARS spectrum of HCl was studied over the pressure range 0.002β1.000 bar and the temperature range 298β1048 K. The broadening coefficients, Ο~p~, are dependent on __J__ at 298 and 550 K but are independent of __J_
molecular beam maser spectrometer with 8 kHz resolution. The nitrogen quadrupole coupling tensot in the principal inertial axis system was determined. The values are eQq,, = 1960 + 2 kHz; @qbb = 188g r 3 kHz and e&cc = -3848 2 4 kHz. Accurate values for the center frequencies for the rotational tran
