The Use of NMR and Mass Spectral Data in the Forensic Laboratory

Abstract

The role of the forensic laboratory in law enforcement is briefly discussed. Not only is it necessary to identify the major constituent of an exhibit, but in many cases valuable intelligence is gained by identifying whatever else is present. This includes other drugs, excipieuts, metals, etc. Therefore, identification of an extremely wide range of chemicals is required. The use of NMR and mass spectral data in the positive identification of such substances is invaluable. Specific examples of these data in identification are discussed.

Nuclear magnetic resonance spectrometry

“…Several reviews concerned with applications of NMR to biochemistry and related subjects summarize recent advances . Reviews of a general nature (54)(55)(56)(57), nitrogen NMR (58), pulse Fourier transform NMR (59, 60), nuclear shielding (61), spectral analysis (62), nomenclature (63), inorganic compounds (64), high resolution NMR theory (65), NMR in combination with other methods (66), correlation tables (67), use of NMR in the forensic laboratory (68), pharmacology (69)(70)(71), and pesticide research (72), and NMR and ESR in liquid crystals (73) have also been presented. Several discussions of 13C NMR (74)(75)(76)(77)(78)(79)(80) in addition to the texts cited above have appeared.…”
