Vibrational spectra of coupled adsorbed molecules
Physical Review B, 1985The general theory of coupled molecular dipoles is applied to the vibrational spectra of interacting molecules on surfaces. Both classical and quantum-mechanical analyses are presented for the infrared-absorption spectrum. Asymmetric (Fano-effect) line shapes are derived for coupled molecules that interact with electron-hole pairs or optical phonons in

Vibrational-vibrational coupling in air at low humidities
The Journal of the Acoustical Society of America, 1986Calculations of sound absorption in air are traditionally based on the assumption that molecular relaxations in nitrogen and oxygen are independent. In binary mixtures of these two gases, however, molecular relaxation is known to be controlled by a very strong vibrational-vibrational (V-V) coupling, which influences both the relaxation times and the ...

Vibrational dynamics of DNA. I. Vibrational basis modes and couplings
The Journal of Chemical Physics, 2006Carrying out density functional theory calculations of four DNA bases, base derivatives, Watson-Crick (WC) base pairs, and multiple-layer base pair stacks, we studied vibrational dynamics of delocalized modes with frequency ranging from 1400to1800cm−1.

Thermomechanically coupled non-linear vibration of plates
International Journal of Non-Linear Mechanics, 1986An analytical method is presented for the analysis of large amplitude thermomechanically coupled vibrations of rectangular elastic thin plates with various boundary conditions. The field of temperature and deformation are assumed to be coupled, and the trasverse and longitudinal deformations are mutually dependent.

Measurements of vibration-vibration coupling in gas mixtures
Symposium (International) on Combustion, 1967A series of experiments were performed on NO−CO, NO−N2 and CO2−N2 mixtures to measure the rate of vibration-vibration (V-V) energy exchange. The experiments were carried out behind incident shocks in shock tubes and cover the approximate temperature range from 800° to 3250°K.

A higher degree of complexity is added by including coupling between electrons and local vibrational modes. Here, we begin by considering the theory for electronic transport through molecular quantum dots in which bosonic modes, e.g. vibrations, are present.

Rayleigh Quotients for Coupled Free Vibrations
Journal of Sound and Vibration, 1994Summary: Based upon the general thin shell theory and basic equations in fluid mechanics, three kinds of Rayleigh's quotients for coupled fluid-structure free vibrations are developed for arbitrary tanks fully or partially filled with (i) inviscid, irrotational and incompressible fluid, with the effects of free surface waves neglected, (ii) inviscid ...
