At present, the relevance of Raman Spectroscopy (RS) as an analytical tool in pharmaceutical sciences is increasingly obvious. RS is a mode of vibrational spectroscopy based on inelastic scattering of laser light and, like infrared spectroscopy (IR), provides detailed molecular structure information (see Figure 1A). However, contrary to IR, it…

Currently, Raman spectroscopy (RS) is rapidly becoming a mature analytical technique in the pharmaceutical world. Thus far, it is used almost exclusively in a stand-alone mode, since coupling with liquid separation methods hardly seemed realistic in practice. However, as outlined in this article, recent developments are quite promising and such…
