Nuclear spin relaxation by intramolecular interactions in gases of homonuclear diatomic molecules

Nuclear spin relaxation in liquids and gases

The aim of this report is to cover the progress of work in the field of magnetic relaxation and self-diffusion in liquids and gases over a period of twelve months from June 2005 to May 2006, and is a continuation of the report given last year. As in previous periods, this review is limited to work on comparatively simple liquids and solutions of physico-chemical and chemical interest, as public...

Estimations of Rotational Relaxation Parameters in Diatomic Gases

The problem of redistribution of translational and rotational energy has been solved for diatomic gases within the framework of the Chapman-Enskog method and the Parker model in the general case of the arbitrary energy exchange ratio. The nonequilibrium gasdynamic equations, transport coefficients and relaxation time have been found for rotational-translational processes in a diatomic gas. The ...

Spectroscopic investigation of spin zero homonuclear and heteronuclear molecules

In the present article, we introduce a model to investigate the energy spectrum of a relativistic rotor by considering the Klein-Gordon Hamiltonian. Rotational spectral lines are a signature of homonuclear and heteronuclear systems and play a key role in understanding diatomic molecules. We show that the energy-correction term arising due to unequal masses influences the line separation. Determ...
