The appearance of doubly charged molecular, fragment and cluster ions in the field desorption and field ionization mass spectra of thiotepa are discussed. A comparison with the field‐desorption mass spectra of some other oxygen‐ and sulfur‐containing compounds is made and the conclusion reached, that the formation of doubly charged fragment [MO] 2+ , [MS] 2+ , and cluster [(MO)M] 2+ , [(MS)M] 2+ ions is a characteristic behaviour of several types of substances containing O and S groups under the conditions of high electric field.
