Negative ion fast atom bombardment mass spectrornetry is used to verify the sequence of ol¡godeoxyri~nucleotides containing a single modified nucleotide. Both the position in the sequence and the rnolecular weight of the modified nucleotide can be determined from the 3 and 5'-phosphate sequence ions

✦ Synopsis
Abstract
A new technique using negative‐ion fast atom bombardment mass spectrometry for the analysis of xanthates and related compounds is described. Electron impact and positive‐ion fast atom bombardment mass spectrometry produced no structurally related fragment ions or observable molecular ions at the expected m/z values. It was demonstrated that negative‐ion fast atom bombardment ionization was the most suitable method of ionization for structure elucidation studies for the compounds described.

## Abstract The fragmentation patterns of __N__‐phosphoamino acids in negative‐ion fast atom bombardment mass spectrometry (FABMS) showed different characteristics to those in positive‐ion FABMS. Six typical __N__‐diisopropyloxyphorphorylamino acids all had intense [M − 1]^−^ peaks, and they underw
Applicability of negative ion fast atom bombardment (FAB)-tandem mass spectrometry (MS/MS) was examined in trace mixture analyses and structural assignments of some isoprenoid diphosphates. Negative ion FAB-MS spectra using a glycerol matrix of these isoprenoid diphosphates showed predominantly mole
