The mass spectra of 3-quinuclidone, methyl 5-ketoquinuclidine-2-carboxylate, ethyl 3- and 5-ketoquinuclidine-2-carboxylates, benzo(b)-3-quinuclidone, and ethyl 3-ketobenzo(b)quinu-clidine-2-carboxylate were investigated. The fragmentation of the investigated compounds is realized through the open form of the molecular ion with cleavage of the bridge bond containing the carbonyl group and with subsequent elimination of carbon monoxide. The principal disintegration mechanisms were confirmed with isotope labels.
