The spectral profile of the coll is ion-induced translational light scattering by gaseous CH4 Determination of the pair polarizability anisotropyt

چکیده
The two-body purely translational, collision-induced light scattering spectra of CH4-CH 4, CH4-Ar, and CH4-Xe at 295 K are deduced by subtraction of the collision-induced rotational Raman scattering component from the total spectrum. For CH4-CH4, the zeroth moments of the total and purely translational spectrum are 205"4 ___ 14A 9 and 203"8 _ 14,~ 9 respectively. The CH4-CH 4 translational moments are used to evaluate the parameters in an expression for the pair polarizability anisotropy. Although some ambiguity exists, a model is thus obtained for the ex t ra -DID contributions which is consistent with the inert gas case.

متن کاملThe three body correlation spectrum in collision induced light scattering by isotropic molecular gases
The three body correlation spectra in the collision induced light scattering by gaseous At, CH4, CF4 and SFa at 295 K are reported. The zeroth and second frequency moments are compared with calculations based on a pairwise additive triplet cluster polarizability. It is found that the experimental results may be accounted for with the use of the first order dipole-induced dipole model for the po...

A simple, precise, rapid and low-cost potentiometric method for diclofenac determination in pharmaceuticals is proposed. A new diclofenac-sensitive electrode was constructed by incorporating the diclofenac ion pair complex with butyl rhodamine B into graphite matrix. The electrode exhibited a linear response over the concentration range of 1 × 10-4 – 5 × 10-2 mol L-1, a detection limit of 3.9×1...
