Electronic Raman Spectra. VII. Raman Spectra of the Lanthanides
Canadian Journal of Chemistry, 1971Additional experimental data are reported on electronic Raman scattering of trivalent lanthanides, making the observation of this effect of the series nearly complete. The bulk of the information now available points to the fact that the intensity of electronic Raman transition is strongest for the rare earth ions in the middle of the series. The most

Laser Raman spectra of glucagon
Archives of Biochemistry and Biophysics, 1979Abstract Laser Raman spectroscopy study indicates that in concentrated fresh acidic solution (30 mg/ml), glucagon remains predominantly α-helix and not random-coil. The splitting of the amide III band into three components in the crystal at 1262, 1275, and 1295 cm −1 is due to the α-conformation as expected.

First-order Raman spectra of wurtzite GaN made from natural Ga and isotopically pure ${}^{15}\mathrm{N}$ and natural N (99.63% ${}^{14}\mathrm{N}$) were measured at low temperature. The Raman frequencies of the polar optical phonons [${A}_{1}(\mathrm{TO},\mathrm{LO})$, ${E}_{1}(\mathrm{TO},\mathrm{LO})$] shift according to the inverse square root of ...

The Raman spectra of selenomethionine and selenocystine
Journal of Inorganic Biochemistry, 1981The trace element selenium is known to be a part of the enzyme glutathione peroxidase (glutathione-hydrogen peroxide oxidoreductase, E.C.1.11.1.9). Studies have shown that selenium in the enzyme exists in at least two forms or oxidation states. It is probable that selenium has been incorporated into the enzyme as the selenocysteine amino acid.

Raman spectra of graphene ribbons
Journal of Physics: Condensed Matter, 2010Raman spectra of graphene nanoribbons with zigzag and armchair edges are calculated within non-resonant Raman theory. Depending on the edge structure and polarization direction of the incident and scattered photon beam relative to the edge direction, a symmetry selection rule for the phonon type appears.

Resonance Raman spectra of chloroperoxidase
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1976Resonant Raman spectra of native and reduced chloroperoxidase are presented and the principal features are tabulated. Comparisons are made with the spectra of other heme proteins. The correlation proposed for certain Raman “marker band” positions and spin or oxidation state is found not to hold for these spectra.

Hemoglobin: Resonance Raman spectra
Biochimica et Biophysica Acta (BBA) - Protein Structure, 1972Abstract Raman spectra have been recorded for several hemoglobin derivatives in dilute solution. They exhibit a complex set of bands, arising from vibrations of the heme groups. Two of the bands offer promise as structural probes, inasmuch as their intensities correlate inversely with the degree to which the iron atoms are out of plane.

The Raman spectra of Ba2NaNb5O15 single crystals were recorded for various scattering configurations from 77°K to 843°K. Splittings of the vibrational modes due to electrostatic and anisotropic forces were found to be small. The line-widths of the 650 cm-1 and the 280 cm-1 modes were found to increase with increasing temperature.
