Energy-level diagram showing the states involved in Raman spectra. Raman spectroscopy (/ ˈ r ɑː m ən /) (named after physicist C. V. Raman) is a spectroscopic technique typically used to determine vibrational modes of molecules, although rotational and other low-frequency modes of systems may also be observed. [1]
In 1969, Bruker launched the first commercial Fourier transform NMR spectroscopy system (FT-NMR) and in the 1970s the company was the first to commercialize a superconducting FT-NMR. Later, the company would expand their product range with MRI, FTIR and FT-Raman spectrometers and with mass spectrometers. [7]
Bruker Introduces Proprietary IRIS TERS Probes High-Contrast, Proven TERS Probe Tips for Complete Innova-IRIS TERS Solution BOSTON--(BUSINESS WIRE)-- Bruker announced today at the 2012 Materials ...
The effects due to solvent on stabilizing the structures (conformers and zwitterionic species) of amino acids and peptides and the corresponding effects seen in the vibrational circular dichroism (VCD) and Raman optical activity spectra (ROA) have been recently documented by a combined theoretical and experimental work on L-alanine and N-acetyl ...
It states that no normal modes can be both Infrared and Raman active in a molecule that possesses a center of symmetry. This is a powerful application of group theory to vibrational spectroscopy, and allows one to easily detect the presence of this symmetry element by comparison of the IR and Raman spectra generated by the same molecule. [1]
The Raman microscope is a laser-based microscopic device used to perform Raman spectroscopy. [1] The term MOLE (molecular optics laser examiner) is used to refer to the Raman-based microprobe. [ 1 ] The technique used is named after C. V. Raman , who discovered the scattering properties in liquids.
