F. Thibault et al., LINE MIXING EFFECTS IN THE 00-DEGREES-3-00-DEGREES-0 BAND OF CO2 IN HELIUM .1. EXPERIMENT, The Journal of chemical physics, 100(1), 1994, pp. 210-214
The shape of the 00-degrees-3-00-degrees-0 CO2 band in helium has been
investigated at room temperature over an extended range of perturber
pressures (0-140 atm). Various and strong deviations from an additive
superposition of Lorentzian lines have been observed, due to important
line mixing effects enhanced by the specific structure of the R branc
h in this band.
