โœฆ Synopsis

The FAB mass spectra of four sulphonated merocyanine dyes are investigated. Negative ion spectra are superior to those in the positive ion mode. The special structure of merocyanines with an acidic group at one end of the molecule and a basic group at the other leads to significantly different fragmentation pathways for positive and negative ions.

## Abstract Fast atom bombardment mass spectra of a range of involatile mono and disazo sulphonated dyestuffs are presented. Excellent spectra are obtained for dyestuffs containing up to five sulphonate groups. The fragmentations are discussed with special reference to the ions formed by cleavage o

Positive-ion fast atom bombardment mass spectra and linked-scan tandem mass spectra were measured for aromatic iodonium salts. The mass spectra usually contain the intact cation of the iodonium salt as the base peak, fragment ions of lower abundance resulting from simple cleavages or rearrangements,

The positive-ion fast atom bombardment (FAB) mass spectra of stibonium salts have been studied. The spectra exhibit an abundant intact cation ( C ' ) and fragment ions resulting from the loss of R, R' or stable neutral species from the cation. The principal fragment ions in the FAB mass spectra of s
