โฆ Synopsis
We propose a local modes description of stretching motion and enera transfer in photocxcited IzS,, ran der Wa;lls compleses. In a simple local modes model. we find decrcasin, 0 efficiency of vibrationA predissociation as the size of the complex grows. in qualitative agreement with recent esperimcnts.
