D. Frequencies Molecules vibrate (stretch, bend, twist) even if they are cooled to 0 K. This is the basis of infrared/Raman spectroscopy, where absorption of energy occurs when the frequency of molecular... [Pg.8]

Raman spectroscopy has been successfully applied to the investigation of oxidic catalysts. According to Wachs, the number of Raman publications rose to about 80-100 per year at the end of the nineties, with typically two thirds of the papers devoted to oxides [41]. Raman spectroscopy provides insight into the structure of oxides, their crystallinity, the coordination of metal oxide sites, and even the spatial distribution of phases through a sample when the technique is used in microprobe mode. As the frequencies of metal-oxygen vibrations found in a lattice are typically between a few hundred and 1000 cm 1 and are thus difficult to investigate in infrared, Raman spectroscopy is clearly the indicated technique for this purpose.

The Raman spectra of heroin, morphine and codeine (Fig. 7.10) are highly characteristic because of the change in the bands due to the aromatic ring. The FT-IR spectra of these compounds are quite similar. Near-infrared Raman spectroscopy can provide a rapid method for characterising drugs with minimal sample preparation and analysis time.

Surface-enhanced near-infrared Raman spectroscopy has been utilized to study the behavior of nicotinamide adenine dinucleotide on a gold electrode [303]. It has been found that either adenine or nicotinamide moiety changes its adsorption states during potential scanning. [Pg.874]

Complementary to infrared, Raman spectroscopy (2) provides unique information about molecular structure. Whereas polar groups and antisymmetrical vibrations of molecular fragments are better detected by IR spectroscopy, Raman spectroscopy is more suitable for the identification of unpolar groups and symmetrical vibrations of molecular fragments. However, dispersive Raman spectroscopy did not find general acceptance in the analytical laboratory during... [Pg.73]
