Raman Spectra of Coals

Nature Physical Science, 1971
RECENTLY published Raman spectra of carbons1–3 suggest that it would be worth applying the Raman technique to the study of coal. This article reports Raman spectra of unpolished chips of coal and indicates some of the problems encountered as well as the sort of information that might be made available by this method.

Raman spectra of solids

Spectrochimica Acta, 1961
Abstract The Raman spectra of solid inorganic, organic, biological and polymeric substances were obtained with the Cary model 81 spectrophotometer 4 , using the same optics and source of the instrument that are employed for liquid samples. To study the quality of the spectra obtained, several types of sample tubes were tried and the effects of ...

Raman Spectra of Gases

Nature, 1931
USING a stout silica tube capable of standing pressures up to 50 atmospheres as the container, I have successfully photographed the Raman spectra for a number of gases. Perhaps the most interesting case studied is that of acetylene; wave-number shifts 1974 and 3372 are observed in agreement with the vibration numbers 1975 and 3365 recently derived by ...

Raman spectra phthalocyanines

Journal of Molecular Structure, 1986
Abstract Raman spectra of amorphous phthalocyanine thin films have been studied. Theoretical and experimental correlations in polarization ratios are applied to vibrational assignments of symmetry species and to the problem of molecular orientation in thin solid films.

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.

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.

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.
