## Abstract An experimental and theoretical study of the pressure broadening and the pressure shift of three HCO^+^ rotational lines (j=4β3, 5β4 and 6β5) perturbed by collisions with Ar is presented. The measurements are carried out at 77 K and are compared to closeβcoupling calculations performed

The temperature dependence of lineshift and broadening of the rovibrational transitions R( ) and R(20) of the CO fundamental band, perturbed by Ar, N 2 , O 2 , and H 2 , have been measured with high frequency accuracy and at temperatures between 160 and 270 K in steps of 20 K.
