Abstract
The data from low- and high-resolution mass spectrometry constitute evidence for nonidentical structures of the excited molecular ions of 2- and 3-aroylindoles, and this makes it possible to reliably identify isomeric pairs. The presence of rearranged (M-H-CO)+, (M-OH)+, and (M-H2O)+ ions was noted, and a mechanism for their formation was proposed.
