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

Abstract

A model is developed for the calculation of the inhomogeneous line shapes of electronic transitions of molecules embedded in superfluid liquid 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 experimental spectra yield very good agreement and reasonable values for the model parameters. (C) 2001 American Institute of Physics.
