What can higher-order optical techniques reveal about liquids? This review examines recent advances in employing higher-order electronic and vibrational spectroscopies to study liquid-state dynamics and structure. It addresses recent advances that have been made in recent years in employing higher-order electronic and vibrational spectroscopies to study liquid-state dynamics and structure. Laser technology now enables nonlinear optical experiments that probe higher-order correlation functions in liquids. Laser technology has progressed to the point that it has become possible to perform nonlinear optical experiments that probe higher-order correlation functions in liquids, opening a new window into our understanding of the microscopic details of solution-phase processes. Nonlinear optical experiments that probe higher-order correlation functions in liquids have opened a new window into our understanding of the microscopic details of solution-phase processes. This review is useful to the behavior of liquids.
This review in the Annual Review of Physical Chemistry summarizes recent advances in higher-order optical spectroscopies applied to liquid-state studies. It fits the journal's mission as a review, summarizing progress for physical chemists and researchers in related fields.
