Abstract

Nonlinear spectroscopy has proved to be very useful in learning about dynamic processes in molecular systems. The multiple field configuration allows more information to be obtained than is available from linear spectroscopic or time domain measurements. Results on coherent Raman effects, high field Raman effects, transient three- and four-wave interactions and highly resonant responses of molecules in liquids and solids are presented. Some four-wave effects such as DICE are extremely useful in discerning excited state dynamics. The effects of inhomogeneous line broadening in determining the nonlinear response are also discussed along with some new examples of line narrowing in anticorrelated distributions.
