Raman spectra of polyglycines

Biopolymers, 1969
AbstractThe laser‐excited Raman spectrum of helical polyglycine II has been obtained. Oligomers of polyglycine are in the planar zigzag conformation and their Raman spectra are indicative of the spectrum of polyglycine I. The Raman spectra of polyglycines have bands complementary to the infrared which are sensitive to the conformation of the chain. The

On the Raman spectra of mononucleotides

Journal of Molecular Structure, 1990
Abstract The Raman spectra of aqueous solutions of 5′-mononucleotides derived from adenine, uracil, guanine and cytosine have been examined in the 1150-950 cm−1 spectral region. The origin of some common bands, not previously reported, has been discussed by taking into account isotopic frequency shifts, depolarization ratios, normal coordinate ...

Raman spectra of K2CuF4

Solid State Communications, 1976
Abstract The crystal structure of K 2 CuF 4 has been studied by means of Raman scattering. The structure is found to belong to the space group D 4 h 5 rather than D 4 h 17 of K 2 NiF 4 between 2 and 800 K because of the distortion arising from the “orbital ordering effect”.

Raman spectra of HfS3

Solid State Communications, 1980
Abstract We report the first order Raman spectra of a one-dimensional semiconducting compound HfS 3 at 300 and 77 K. The detected phonons are associated with the different point group symmetries involved in the crystal's structure.

RAMAN SPECTRA OF ALKALI HALIDES

1965
Raman spectroscopy is a powerful tool for the study of the structure of matter and the physicochemical problems of the crystalline states of matter. However, in the case of cubic crystals, because of the symmetry properties, most and in some cases all the fundamental modes of vibration are inactive in the Raman effect.

The Raman Spectra of the Deuteromethanes

The Journal of Chemical Physics, 1936
The four deuteromethanes were prepared. Their vibrational Raman spectra were photographed under high dispersion. A total of 20 lines were analyzed. A discussion, in the light of the general theory, is given of a sequence of observed overtones.

The Raman spectra of ferrocene

Chemical Physics Letters, 1969
Abstract Raman spectra of ferrocene single crystals are presented and their assignment given. Some of the controversies regarding different assignments given by Lippincott and Nelson and by Stammreich are resolved.

The Raman spectra of bromoform

Spectrochimica Acta Part A: Molecular Spectroscopy, 1979
Abstract In this work the Raman spectrum of bromoform is recorded at various temperatures in the pure compound and in solution in carbon tetrachloride and the features shown by some of the bands are considered in the light of previous spectroscopic data interpretations.
