The mass spectra of a series of isatin, oxindole and 2‐oxo‐3‐indolyl derivatives have been investigated using high resolution and deuterium labelling techniques. The fragmentations involve the sequential loss of a number of neutral molecules and the results show that the concept of charge localisation can be applied with success to explain the fragmentation processes even in these polyheteroatom species.
