Effect 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 کاملSymmetry of extremely floppy molecules: Molecular states beyond rotation-vibration separation.
Traditionally, molecules are theoretically described as near-static structures rotating in space. Vibrational motion causing small structural deformations induces a perturbative treatment of the rotation-vibration interaction, which fails in highly fluxional molecules, where all vibrational motions have amplitudes comparable in size to the linear dimensions of the molecule. An example is proton...
متن کاملRotation-Vibration States of Triatomic Molecules at Dissociation
Nuclear motion resonant states of triatomic molecules are calculated using an L2 method known as Complex Absorbing Potential (CAP). This method is implemented in a new program named RES3D which includes a new automatic procedure to obtain the resonant states’ energies and lifetimes, allowing for the first time the quantification of the results’ accuracy through a consistency test across differe...
متن کاملOn the Use of Quantum Algebras in Rotation-vibration Spectroscopy
A two-parameter deformation of the Lie algebra u2 is used, in conjunction with the rotor system and the oscillator system, to generate a model for rotation-vibration spectroscopy of molecules and nuclei.
متن کاملRotation Vibration Spectrum of the HCl Molecule
One might expect that quantum mechanical calculations capable of predicting the structure of even the simplest molecules would be quite complex. Indeed, solving the Schrödinger equation for the nuclei and all electrons would be a formidable task. Fortunately, this is not always necessary. Because of their large mass difference, accurate results can be obtained while treating the electron and nu...
