Publications Green et al. 1989 Green, S., R. Blackmore, and A. Monchick 1989. Comment on linewidths and shifts in the Stokes-Raman Q branch of D 2 in He. Collision induced widths and shifts for Raman Q-branch transitions of D 2 in He were calculated from S matrices obtained with converged close coupling scattering calculations on an accurate theoretical interaction potential.
Results agree well with experimental values.
Discrepancies between experimental line shifts and theoretical values from an earlier study are traced to a computational error in that work. The effects of vibrational inelasticity and of centrifugal distortion on energy levels and on potential matrix elements, all of which were ignored in the earlier study, are explicitly considered here and found to be small.
