Inhomogeneous line shape theory of electronic transitions for molecules embedded in superfluid helium droplets

Abstract

A model is developed for the calcn. of the inhomogeneous line shapes of electronic transitions of mols. embedded in superfluid liq. helium droplets. This model takes account of the cluster size distribution, and the size dependence of the capture cross section and the resonance frequency. Fits to exptl. spectra yield very good agreement and reasonable values for the model parameters.
