Abstract
A variety of fitting laws have been developed for the purpose of model ling broadening effects in collisional processes, but only a few have been proposed for modelling collision-induced lineshifts in molecules. We analysed accurate stimulated Raman data obtained in several H-2-X mixtures (X: H-2, He and N-2). For the first time, we show that an emp irical law provides a very good representation of collisional lineshif t coefficients in the range 300-1200 K and for J quantum number up to 9.
