Intramolecular vibrational redistribution: from high-resolution spectra to real-time dynamics

Abstract

Intramolecular vibrational redistribution is a fundamental phenomenon observed in polyatomic molecules when sufficiently excited vibrationally. In this paper, results mostly from the last two decades of research on this subject are summarized, obtained either from infrared spectroscopy with a resolution of as high as ##IMG## [http://ej.iop.org/images/1063-7869/55/10/R05/tex_pu_7911_img1.gif] {$ 10^{-4}$} cm ##IMG## [http://ej.iop.org/images/1063-7869/55/10/R05/tex_pu_7911_img2.gif] {$ ^{-1}$} or, in a different approach, by using various pump-probe schemes with a temporal resolution from dozens of picoseconds to subpicoseconds.
