Vibrational dynamics of liquids and solids investigated by picosecond light pulses
A. Laubereau,W. Kaiser +1 more
TL;DR: In this article, a detailed theoretical treatment of different excitation and probing processes are outlined and a variety of results are presented and discussed, including the population lifetime of known vibrational modes and evidence for inter-and intra-molecular interactions.

On vibrational relaxation in liquids
David W. Oxtoby,Stuart A. Rice +1 more
TL;DR: In this article, the relationship between vibrational population relaxation, loss of phase coherence, and the homogeneously broadened spontaneous polarized Raman linewidth is discussed, and a general equation relating there quantities is derived.
Journal ArticleDOI
Dephasing processes of molecular vibrations in liquids
TL;DR: In this article, a model based on semiclassical collision theory is presented to describe the dephasing of vibrationally excited molecules in a liquid, and it is shown that fluctuations of the vibrational frequencies which are caused by the intermolecular interaction, lead to phase relaxation of a coherently excited state.
Journal ArticleDOI
A molecular dynamics simulation of dephasing in liquid nitrogen
TL;DR: In this article, the dephasing of molecular vibrations in liquids is related to certain correlation functions involving only the translational and rotational degrees of freedom; these correlation functions are then determined through a classical molecular dynamics simulation of rigid, nonvibrating molecules.

Journal ArticleDOI
Direct Measurement of the Vibrational Lifetimes of Molecules in Liquids
TL;DR: In this article, a normal molecular vibration is strongly excited by a picosecond light pulse and the rise and decay of the excess population of the first excited vibrational state (electronic ground state) is observed with a delayed probe pulse.

Relations between Raman Spectroscopy and Nuclear Spin Relaxation
TL;DR: Raman spectra and nuclear spin relaxation experiments are both affected by molecular rotation, and the information about molecular reorientation furnished by these experiments is related under certain assumptions, most important of which are the following: (1) the substance is a molecular liquid or gas, and (2) the molecules have either linear, symmetric top, or spherical top symmetry as discussed by the authors.

Vibrational Energy Transfer in Molecular Collisions Involving Large Transition Probabilities
D. Rapp,T. E. Sharp +1 more
TL;DR: In this article, the Schrodinger equation is solved based on a semiclassical collision subject to an assumed form of potential, to get exact transition probabilities in a molecular collision at low velocities.

Resonant and Near‐Resonant Vibrational—Vibrational Energy Transfer between Molecules in Collisions
TL;DR: In this article, a semiclassical calculation of the probabilities of resonant and near-resonant vibrational energy interchange in molecular collisions is performed by means of a collision model similar to that used in vibrational transfer.
