Transmission Raman Spectroscopy

Transmission Raman Spectroscopy

Transmission Raman spectroscopy is a variant of Raman spectroscopy beneficial in probing bulk content of diffusely scattering samples. Although it was demonstrated in the early days of Raman spectroscopy it was never exploited in practical settings, probably due to limitations of technology at the time. It was rediscovered in 2006, where the authors showed it was capable of allowing Raman spectroscopy through many millimetres of tabletted or powdered samples. In addition, this research has also identified several highly beneficial analytical properties of this approach, including the ability to probe bulk content of powders and tissue in the absence of subsampling and to reject Raman and fluorescence components originating from the surface of the sample.
