intensity molecular ions. The purity of the products and their molecular weights were checked by a novel ionization technique in mass spectrometry, fastatombombardment (FAB) mass spectrometry. FAB spectra were obtained from underivatized bile salts. The spectra were characterized by ions formed by attachment of a proton or an alkali ion to the bile salt to give intense M+H, M+Na, or M+K ions, which then
