Resonance Raman characterization of proteorhodopsin's chromophore environment

Article Abstract:

Resonance Raman spectra of proteorhodopsin (pR) excited with 532-nm light indicate that there are two subpopulations of pR within the sample solubilized in octylglucoside detergent and maintained in a light-adapted state in a spinning Raman cell. The two populations exhibit two distinct chromophore environments, as evidenced by two sets of split peaks.

Elastic constants and related mechanical properties of the monoclinic polymorph of the carbamazepine molecular crystal

Article Abstract:

Brillouin scattering is used for probing the acoustic constants and elastic constant tensors of the monoclinic polymorph of the drug carbamazepine (CBZ III). Cauchy's ratio from the elastic constants has suggested that many-body forces of dispersive interactions have contributed to the lattice anharmonicity of CBZ III.
