Integral cross sections and pressure-broadening coefficients have been measured by molecular beam scattering and by high-resolution infrared spectroscopy, respectively, for the acetylene-argon system. A new potential energy surface (PES) is proposed to describe structure and dynamical properties of this prototypical weakly bound complex. The PES has been… (More)
Using diode-laser spectroscopy, the intensities of 58 lines of the v(1) + v(1/2) - v(1/2) band and 36 lines of the 2v(1) - v(1) band of OCS have been measured. The corresponding band strengths S(0)(v) and the vibrational transition dipoles micro(v) have been derived through least squares fitting of these individual intensities. The band strengths values… (More)
This work presents a synthesis of our results concerning line intensities and self-broadening coefficients for ClCN in the diad (nu1, 2nu 2 0). Absolute band strengths have been determined. The influence of the perturbation in these band strengths due to a Fermi resonance between the 10(0)0 and 02(0)0 levels has been analyzed.
Kr-broadened halfwidths of twenty-eight lines in the nu(1) band of OC(32)S have been measured from absorption spectra recorded at room temperature with a tunable diode laser spectrometer. The results are compared to values calculated on the basis of the Anderson-Tsao-Curnutte theory and an improved semiclassical impact model developed by Robert and Bonamy.… (More)
Absolute intensities have been measured for 26 lines of C2H4 in the nu7 fundamental transition, using a tunable diode-laser spectrometer. These lines with 3< or = J"< or = 21, 2< or = Ka< or = 4, 2< or = Kc< or = 20 are located in the spectral range 920-980 cm(-1). The intensities have been measured by using two methods: the equivalent width method (EWM)… (More)
The pressure-induced Xe shifting and broadening coefficients for five lines of 12CH(3)D in the nu(3) band near 7.5 microm have been measured using a tunable diode-laser spectrometer. The frequency shift was determined from the simultaneous record of the Xe-broadened line and the same line of pure CH(3)D at low pressure. Comparisons are made with the results… (More)
Preliminary results for collisional broadening are reported for two lines P(8) and R(32) of the nu3-nu1 band of CS2 in mixture with O2 and air. These values and previous results for CS2-N2 enable us to compare the broadening coefficients directly obtained for CS2-air with those derived from CS2-N2 and CS2-O2.
