Gemstone Identification Using Raman Spectroscopy (PDF)

April 01, 2004

Articles

Raman microspectroscopy is an ideal method for the examination of marketable gemstones because of the lack of sample preparation involved and the nondestructive nature of Raman analysis.

NIR-CI adds a completely new dimension to conventional spectroscopy.

Tautomerism and Expert Systems in Spectroscopy (PDF)

April 01, 2004

Articles

Because tautomers often cannot be isolated as single isomers, spectroscopists should always anticipate possible tatomeric forms that can complicate the interpretation of their spectra. This involves the use of spectral databases and tautomerically enabled search algorithms.
