title: Mass spectrometric studies of the pterocarpan skeleton.
abstract: The mass spectrometric characteristics of the pterocarpan skeleton have been studied with the aid of metastable decomposition (CAD-MIKES), high resolution mass measurements and specific deuterium labeling. New structural rotations have been postulated for the [M - H](+) ions which can explain the fragmentation routes for the pterocarpan skeleton.
