✦ Synopsis

The high-re~lution spectra ofH2'60, H2"O. HDr60. HD'aO. D2r60, and D2 180 isolated in argon and krypton matrices are reporkd in the IO-60 cm-r region. The high resolution is obtained by observin_e very ddu te mixtures of watcr in the rare gases. NO discrete absorbancrs attributable to pure argon or krypton are found in this regton. In aU cases the relatwe gas-matrix shifts of the isotapimers are consistent with the rotation-translation couphng model. The lineaidtbs arc found 10 correlate with rotation-translation coupling_ The rntegrated inrcnsity of the l(1.1) -O(O.0) rransition of HDO exhibils a temperature dependcnoc which does not deviate syniticantly from that expected from ;i Boltzmann dlstrtbution in rigid rotor energy levels.

Previous measurements of asymmetries of the profiles of argon-broadened HF lines at moderate perturber densities (pressures higher than 10 atm) have been confirmed and extended by high-resolution Fourier transform spectroscopy. In some cases, the asymmetries observed here are of opposite sign when c

The test of an interaction potential for HF-argon recently determined from the spectroscopy of the Van der Waals complex requires accurate experimental widths and shifts cross sections. Since inconsistencies existed between previous measurements, collisional lineshapes were studied at T = 296 K by h
