In a classical treatise, Rautian and Sobelman discussed a number of Dicke-narrowed spectral profiles incorporating strong (hard) and/or weak (soft) velocity-changing collisions statistically dependent on (correlated with) or independent of dephasing (pressure-broadening) collisions. More recently, the effects of speed-dependent broadening and shifting have been evident in accurately measured Dicke-narrowed line shapes analyzed in the limits of uncorrelated soft or hard or partially-correlated hard collision models. Combined soft and hard collision speed-dependent profiles have also been proposed in the uncorrelated and fully correlated limits, which we herein generalize for partial correlations applied to the case of Ar-broadened HF.
