Ultrafast laser methods continue to have impact on the physical chemistry research of isolated molecules, liquids, new materials and biological structures even as the laser technology presses toward the attosecond and x-ray regimes. This talk will focus on nonlinear spectroscopy, particularly its impact on biophysical chemistry. The recent developments in multidimensional nonlinear optical and infrared spectroscopy are realizing their promise for advances in the visualization of time dependent structure changes and fundamental physical processes in complex systems ranging from liquids and aqueous solutions to proteins, large biological assemblies such as HIV inhibitor drugs and macroscopic amyloid fibrils.
