Asphaltenes extracted from seven different crude oils representing different geological formations from around the globe were analyzed using the Raman spectroscopic technique. Each spectrum is fitted with four main peaks using the Gaussian function. On the basis of D1 and G bands of the Raman spectrum, asphaltene indicated an ordered structure with the

Abstract The Raman spectrum of tellurium was measured at room temperature and the temperature of liquid nitrogen. Five peaks were seen at both temperatures which can be associated with the normal modes of vibration of the D 3 point group for a three-atom molecule.

Two of the 3 Raman-active fundamentals of UF6 have been observed at 666.6±0.3 (ν1) and 535±5 cm—1 (ν2) for a gaseous sample. The new value for ν2 is in good agreement with the value 532 cm—1 obtained earlier by Gaunt from infrared combinations. The sample of UF6 was contained in a Pyrex Raman tube and was irradiated for many hours with 4358 A light ...

The rotational and rotation-vibrational Raman spectra of gaseous ethane at 1–3 atm. pressure have been photographed with a spectral resolution of approximately 1 cm.−1. Analyses of the rotational structures of the ν1 and ν2 totally symmetric bands were carried out; only the Q branch of the ν2 band was observed. The structures of the degenerate ν10 and

Abstract The general problems involved in the Raman study of monoclinic crystals are examined, and a simple procedure is described for the analysis of the vibrational spectrum of such crystals which permits the modes predicted by group theory to be unambiguously assigned.

Raman Spectrum of Monodeuteroethylene
Nature, 1937MONODEUTEROETHYLENE has been prepared (J.C.J.) in two different ways. Starting from vinylbromide and deuterium bromide, obtained by the action of deuterium oxide on redistilled phosphorus penta-bromide, the monodeuteroethylenebromide was prepared. This compound was submitted to the action of zinc and yielded monodeuteroethylene.

The raman spectrum of phosphorus
Proceedings of the Indian Academy of Sciences - Section A, 1935The Raman spectrum of yellow phosphorus as vapour, liquid, solid, and solution in carbon disulphide has been obtained. Only small changes in frequency are observed while passing from solid to liquid and to vapour, indicating the non-polar character of the molecule.

The Raman spectrum of cyclohexanol
Proceedings of the Indian Academy of Sciences - Section A, 1963The Raman spectrum of cyclohexanol has been studied in detail in the liquid state at 30° C. and at about 68° C. and in the solid state at about 13° C. The O-H stretching frequency of cyclohexanol has been found to extend from 3106-3571 cm.-1 in the liquid state at 30° C. and from 3204-3652 cm.-1 at 68° C.

Raman Spectrum of Triethylborane
The Journal of Chemical Physics, 1957Frequency shifts and polarization data are reported for the Raman spectrum of liquid triethylborane, B(C2H5)3. By comparison with the spectra of trimethylborane and ethane, tentative assignments are made for most of the observed bands.
