Cotton-Mouton constant effect

It can easily be seen that in the absence of the vibronic coupling all the parameters 0G3/2(r, p), Q%n(T, /3), and Q n(T, P) are equal to one, and the Cotton-Mouton constant in this approximation is a quadratic function of the inverse temperature, similar to that inherent to molecules with nonzero magnetic moments and with anisotropic polarizability and magnetic susceptibility. The vibronic interaction modifies the temperature dependence by means of the temperature-dependent reduction factors, a part of which was discussed in the investigation of the Kerr effect. 

The Cotton-Mouton effect, magnetic anisotropy, and charge localization of 2,4,6-tris(dimethyl-amino)-1,3,5-triazine compared with 1,3,5-triazine have been examined <91JST(248)20l>. Dilute solution Kerr and Cotton-Mouton constants were measured for both 1,3,5-triazine and 2,4,6-tris(dimethylamino)-l,3,5-triazine. These constants were then used to derive experimental values for the optical-frequency polarizability anisotropies, and more importantly the magnetic anisotropies of... 

The experimental parameter that may give quantitative information on the magnetizability polarizability to second order in the electric field is the Cotton-Mouton constant, responsible for the Cotton-Mouton effect (CME), i.e., the birefringence of light in gases in a static magnetic field [15-19],... 

The key is the Cotton-Mouton, or magnetically induced birefringence experiment. If the multipole analysis of induced effects, as outlined in 2 is justified then it may be shown ) that the Cotton-Mouton constant (jJZ) is proportional to g2 in fact... 

Cotton-Mouton effect), NMR chemical shift and coupling constants, the optical rotation of polarized light and correlation coefficients between different properties. Extensions to incorporate long-range interactions have also been elaborated11 and it has even been possible to adapt RIS theory for the description of the dynamics of transitions between rotational isomeric states.12,13...
