Abstract
Abstract Laser desorption/laser ionization time-of-flight mass spectra of 3-indoleacrylic acid are described. These mass spectra are found to contain an ion peak at m/z 286 which is higher than the m/z value corresponding to the molecular ion (m/z 187). This anomalous peak is not found in the electron impact mass spectrum of this compound. Investigations of possible origins of this feature are discussed.
