title: Positive and negative ion fast atom bombardment mass spectra of some penicilloic acids.
abstract: The technique of fast atom bombardment mass spectrometry has been shown to be capable of producing molecular weight and useful fragmentation information from a selection of penicilloic acids. In addition, the technique has been shown to give similar information on alkali metal salts of penicilloic acids.
