We propose a simple, general, and accurate formula for analyzing the tunneling between classical configurations of a non-planar molecule in a gas medium, as a function of the thermodynamic parameters of the gas. We apply it to two interesting cases: i) The shift to zero frequency of the ...

THE following is an attempt to calculate the number of molecules of helium in unit volume directly, that is, without assuming Avogadro's hypothesis and the known value of the number of molecules of any gas per unit volume.doi:10.1038/080039a0GHOSEPNature...
Spectroscopy of atoms and molecules in gases: Corrections to the Doppler-recoil shift 来自 Semantic Scholar 喜欢 0 阅读量: 20 作者:MP Haugan,FV Kowalski 摘要: We analyze the excitation by an electromagnetic wave of a two-level molecule (or atom) within a rarefied gas. This process differs ...
Method of separating molecules in phase by gas adsorption using solid inorganic adsorbents agglomerated mesoporous distribution was narrow and Calibrated This invention relates to a new family of inorganic solids narrow and calibrated mesopore distribution which are agglomerated with a binder; These solids ...
Specially, cryptophane A, the smallest of the series exhibited an amazing affinity towards methane. This work aims to determine the feasibility of using cryptophanes as new chemical receptors in gas sensor applications. For this, the behaviour of cryptophanes deposited on substrates and put in ...
The gas-phase process of fragmentation of molecules under electron impact was used as a general reaction series for all volatiles. In terms of information theory, the mass spectrum represents the distribution of probabilities of the formation of ions of each type, and the information entropy of ...
The Brownian motion of a hard spherical particle in a gas whose molecules interact only with the particle but not with each other is considered from three points of view. (a) The generalized Fokker‐Planck equation for the process is derived by the classical method of Lord Rayleigh. (b) The...
In addition, the time‐correlation function of molecules in gas mixtures is examined. The corresponding diffusion coefficient decreases with increasing the concentration of the heavy species whereas it increases with the concentration of the light species. 展开 ...
We present a detailed analysis of the two-channel atom-molecule effective Hamiltonian for an ultracold two-component homogeneous Fermi gas interacting near a Feshbach resonance. We particularly focus on the two-body and many-body properties of the dressed molecules in such a gas. An exact result...
