Intra-collision Effects in the Collision-broadening of Spectral Line Profiles
Some details of events occurring during collisions that affect the profiles of collision-broadened spectral lines are reviewed. Emphasis is on the impact and quasi-static approximations. Rotational level mixing and collisional propagation are shown to be important processes. The general principles are illustrated through consideration of the infrared spectrum of the hydrogen molecule. Collision...
متن کاملNanoporous materials.
The current review article attempts to cover the field of nanoporous materials, thereby materials with voids of the order of 1 nm to 100 nm or even larger. Concepts, that have an effect on a more general basis, are introduced and the common features among the different classes of nanoporous materials are demonstrated enabling understanding their formation and stability. It is seen that the most...
متن کاملExciton Dephasing and Thermal Line Broadening in Molecular Aggregates
Using a model of Frenkel excitons coupled to a bath of acoustic phonons in the host medium, we study the temperature dependence of the dephasing rates and homogeneous line width in linear molecular aggregates. The model includes localization by disorder and predicts a power-law thermal scaling of the effective homogeneous line width. The theory gives excellent agreement with temperature depende...
متن کاملUnderstanding diffusion in nanoporous materials.
Can we predict diffusion behavior of molecules in confinement by looking at the match between the molecule and the structure of the confinement? This question has proven difficult to answer for many decades. As a case study, we use methane and a simple model of ellipsoids to arrive at a molecular picture that allows us to make a classification of pore topologies and to explain their diffusion b...
