Research in condensed phase structure and dynamics includes new molecular beam-liquid surface scattering experiments. This research directly probes fundamental gas-liquid interactions at the molecular level. Very little is known about the trapping and solvation of gas phase molecules by a liquid surface, not to mention chemical reaction mechanisms. In other work, dielectric relaxation experiments and complementary theoretical studies provide new information about the dynamics of rotational motions and conformational changes in liquids. Modern NMR experiments probe relaxation phenomena in both solids and solutions.
