Abstrakt: The fragmentation pathways of some 4,5-dihydro-1,2,4-benzothiadiazepine-1,1-dioxide derivatives are discussed on the basis of metastable transition data, exact mass measurements and labelling experiments. These compounds show several primary fragmentation processes: M  SO2, M  OH and one involving an intramolecular oxygen migration (M  CH3NO). [ABSTRACT FROM AUTHOR]
