Structure and nonlinear optical properties of copper phthalocyanine thin films

Abstract
We report the observation of off-resonance electronic energy transfer from an excited rhodamine 6G molecules to an azulene molecule in solution. The process requires the coupling of the radiation field in the transfer process. We demonstrate that the relation YAcCI1"2 between the acceptor's induced fluorescence intensity and the laser intensity, predicted by Jortner et al. is observed.
