Notes:
Different methods of calculations are compared to experiments at 77 K for the broadening Γ and shift s of some HCO+ rotational transitions by collisions with Argon. Capture method and Anderson, Tsao, and Curnutte (ATC) method with straight line trajectories are both not able to reproduce the trend of Γ with J. A discussion of the origin of such a discrepancy allows to obtain better insights into the different causes of collisional relaxation. Quite good agreement is obtained by both a hybrid method or ATC calculations using a more realistic translational dynamics. However, some discrepancy still exists for high J values. © 1999 American Institute of Physics.
