Vibrational relaxation in the condensed phase.
نویسنده
چکیده
A modified Landau-Teller equation for vibrational relaxation in the condensed phase is proposed. This equation differs from previous approaches by accounting for the fluctuations of the energies of the vibrational levels that result from the interactions with the surroundings (bath). In the conventional approach the effects of the bath are only included in the coupling between the relaxing and accepting vibrational modes. It is shown that the additional inclusion of the fluctuations of the energy levels can lead to a dramatic change of the vibrational relaxation rate.

From isolated molecules to biomolecules
We address the dynamics of electronicÈvibrational excited states in isolated molecules, clusters, condensed phase and biosystems, which pertain to the phenomena of energy acquisition, storage and disposal as explored from the microscopic point of view. The advent of femtosecond dynamics opened up new horizons in the exploration of chemical and biophysical processes on the timescale of nuclear m...
متن کاملClassical Approximation to Nonradiative Electronic Relaxation in Condensed Phase Systems
We present a study of the classical limit of nonradiative electronic relaxation in condensed phase systems. The discrete Hamiltonian representing an impurity in a condensed phase environment is mapped onto a continuous form using the Meyer-Miller approach. The classical electronic relaxation rate is obtained within the framework of the reactive flux formalism and is compared to the fully quantu...
متن کاملEffect of molecular rotation on the vibration-vibration energy transfer in condensed media.
The purpose of the present communication has been to present the derivation of the vibrational relaxation rate constant for the case in which both phonons and the molecular rotation (three-dimensional) participate in the vibrational relaxation and to study the effect of molecular rotation on the vibration-vibration energy transfer in the condensed phase. The experimental results of vibration-vi...
متن کاملVibrational relaxation and decoherence in structured environments: a numerical investigation
Vibrational relaxation is a key issue in chemical reaction dynamics in condensed phase and at the gas-surface interface, where the enviroment is typically highly structured and cannot be condensed in a simple friction coefficient. Rather, full knowledge of the coupling of the molecular oscillator to the environment is required, as typically subsumed in the so-called spectral density (of the env...
متن کاملExciton-induced lattice relaxation and the electronic and vibrational spectra of silicon clusters.
The geometrical structures and electronic and vibrational spectra of silicon clusters with 20, 60, and 70 atoms are investigated. Using a first-principles quantum-molecular-dynamics method we obtain the equilibrium structures, and study the effects of an exciton-induced lattice relaxation in these systems. The relaxation induced by the exciton may result in a strong distortion of metastable str...
