Dynamics in nanostructured liquids and surfaces probed with nonlinear infrared and optical spectroscopies
Abstract/Contents
- Abstract
- Many condensed phase systems with complex nanostructure are regularly being developed to address important technological problems. Although the systems may appear static on a macroscopic level, at the molecular level their structure is constantly evolving on ultrafast time scales. However, because these materials are new and more complex than the existing ones, much is still unknown about the local structures and dynamics that give rise to their function. Nonlinear infrared and optical spectroscopies are a powerful class of methods that measure the ultrafast dynamical fluctuations occurring in molecular systems. These methods use short femtosecond pulses of light to perturb and subsequently probe the optical properties of a material system through interactions with molecular properties such as vibrations or molecular polarizabilities. Polarization-selective pump-probe (PSPP) and two-dimensional infrared (2D IR) spectroscopies respectively measure the orientational dynamics and vibrational frequency dynamics of a vibrational probe molecule, which can serve as a reporter of the surrounding structure. Optical Kerr Effect (OKE) spectroscopy measures the collective polarizability dynamics of a molecular ensemble, providing information on collective orientational dynamics. Using these methods, the dynamics in three classes of molecular systems, an ionic liquid, mesoporous silica, and a dipolar liquid, were revealed.
