## Abstract A new technique using negativeβion fast atom bombardment mass spectrometry for the analysis of xanthates and related compounds is described. Electron impact and positiveβion fast atom bombardment mass spectrometry produced no structurally related fragment ions or observable molecular io
## Abstract The negative ion mass spectra of sulphur, dinitriles and their mixtures were studied. The abundance of negative ions of sulphur was almost comparable to that of positive ions. In the negative ion mass spectrum of a mixture of sulphur and dinitrile, intense and characteristic peaks of [M
Negative ion fast atom bombardment mass spectrornetry is used to verify the sequence of olΒ‘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
