Vibrational relaxation of CH3F in inert gas matrices

Vibrational Relaxation and Electronic Energy Transfer of N2 Aggregates in Solid Rare Gas Matrices

Vibrational energy relaxation in proteins.

An overview of theories related to vibrational energy relaxation (VER) in proteins is presented. VER of a selected mode in cytochrome c is studied by using two theoretical approaches. One approach is the equilibrium simulation approach with quantum correction factors, and the other is the reduced model approach, which describes the protein as an ensemble of normal modes interacting through nonl...

Vibrational relaxation of trapped molecules

Vibrational relaxation of trapped molecules due to collisions with cold atoms is investigated using the results of quantum-mechanical scattering calculations. Trap loss is analyzed using an exactly solvable kinetic model that includes direct collisional quenching and an indirect process of vibrational predissociation. At low atom density, the relaxation is due primarily to collisional quenchin...

Vibrational relaxation of CH3I in the gas phase and in solution.

Transient electronic absorption measurements reveal the vibrational relaxation dynamics of CH(3)I following excitation of the C-H stretch overtone in the gas phase and in liquid solutions. The isolated molecule relaxes through two stages of intramolecular vibrational relaxation (IVR), a fast component that occurs in a few picoseconds and a slow component that takes place in about 400 ps. In con...

Inert gas accumulation in sonoluminescing bubbles

In this paper we elaborate on the idea @Lohse et al., Phys. Rev. Lett. 78, 1359–1362 ~1997!# that ~single! sonoluminescing air bubbles rectify argon. The reason for the rectification is that nitrogen and oxygen dissociate and their reaction products dissolve in water. We give further experimental and theoretical evidence and extend the theory to other gas mixtures. We show that in the absence o...
