Selectivity in resonance Raman spectrometry for phenols

Determination of adrenaline and noradrenaline by resonance Raman spectrometry.

Aminochromes of adrenaline and noradrenaline show resonance Raman scattering at 1480 and 1430 cm(-1) respectively, with Ar(+) excitation. Scattering intensity is a linear function of concentration. Detection limits are 1 x 10(-6)M. Both catecholamines can be determined in a single measurement.

Ultraviolet Raman Spectrometry

Molecular selectivity of graphene-enhanced Raman scattering.

Graphene-enhanced Raman scattering (GERS) is a recently discovered Raman enhancement phenomenon that uses graphene as the substrate for Raman enhancement and can produce clean and reproducible Raman signals of molecules with increased signal intensity. Compared to conventional Raman enhancement techniques, such as surface-enhanced Raman scattering (SERS) and tip-enhanced Raman scattering (TERS)...

Application of resonance Raman spectrometry to the determination of vitamin B12.

The resonance Raman effect has been known for many years’. Its potential for trace analysis was pointed out by Brandmiiller2 in 1959. However, full exploitation of resonance Raman spectrometry did not begin until the development of high power, multiline gas lasers as Raman excitation sources. The recent application of tunable dye lasers as excitation sources3 promises even broader applications ...
