title: Structural characterization of two isomeric dimethoxyindoles of biological interest, using high- and low-energy collisional spectroscopy.
abstract: It is not possible to distinguish isomers of biologically important dimethoxyindoles using electron-ionization mass spectra, but they may be distinguished by collisionally activated dissociation. In particular, energy-resolved mass spectrometry yields the best data for distinguishing between these isomers.
