✦ Synopsis


Spectroscopic techniques were applied to the study of natural and synthetic gems, especially rubies. It is shown that among the spectroscopic techniques available, micro-Raman spectroscopy is the easiest to use and the most efficient. Moreover, this technique can be applied to mounted gems without removing them from the setting. However, complementary methods such as micro-Fourier transform infrared, micro-Γ‘uorescence, electron probe and NMR spectroscopy, were used in order to characterize the gems more thoroughly in order to di †erentiate between natural and synthetic specimens. 1997

Obtaining unknown NMR parameters from experimental spectra of exchanging systems is, from a mathematical point of view, associated with the solution of an inverse problem. Inverse problems are usually solved by iterative procedures and calculations may not always converge and the solutions are rarel
