Rotating samples in FT-RAMAN spectrometers

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 1997
It is customary to rotate samples in Raman spectroscopy to avoid absorption or sample heating. In FT-Raman experiments the rotation is always shown (typically 30-60 rpm) because higher speeds are thought to generate noise in the spectra. In this article we show that more rapid rotation is possible. A tablet containing maleic acid and one made up of sub-

Analysis of milk by FT-Raman spectroscopy

Talanta, 2015
Fat, protein, carbohydrates and dry matter were quantified in commercial bovine milk samples, with the relative standard errors of prediction (RSEP) in the 3.4-6.1% range, using the partial least squares (PLS) method based on Raman spectra of liquid milk samples.

FT-IR and FT-RAMAN investigations of nicotinaldehyde

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2006
The Fourier transform Raman and infrared spectra of nicotinaldehyde were recorded and the observed frequencies were assigned to various modes of vibration in terms of fundamentals by assuming Cs point group symmetry. A normal coordinate analysis was also carried out using a simple valence force field.

FT-Raman investigation of alkaloids in the lianaAncistrocladus heyneanus

Biospectroscopy, 1998
The applicability of the micro-FT-Raman technique for studying alkaloids in vitro and for observing alkaloids in plant cells is demonstrated. This technique is examined using fresh plant material of Ancistrocladus heyneanus, a tropical liana known to produce pharmacologically interesting naphthylisoquinoline alkaloids as secondary metabolites.

FT-Raman spectra of platymonas subcordiformis

SPIE Proceedings, 2007
Raman spectrum of Platymonas subcordiformis was studied by FT-Raman spectroscopy. The results show that the optimum experiment conditions is that making sample lose solvent with centrifuge, excitation laser power for 360mW and accumulating 70 times. The main peaks of the spectrum are located at 556cm-1, 615cm-1, 880cm-1, 960 cm-1, 1112cm-1, 1457cm-1,

FT Raman investigations of fast moving samples

AIP Conference Proceedings, 1998
Fast moving samples were investigated by conventional and FT Raman spectroscopy. Using near infrared excitation of a Nd-YAG laser instead of the visible excitation by gas-lasers the problem of fluorescence was overcome. The double modulation due to sample movement occurring in FT Raman spectroscopy was avoided by application of the step scan technique.
