Experimental and Computational Investigation of Sulfur Chemistry in the DART-MS Gas Stream: Implications for the Interpretation of the Mass Spectra of Organic Disulfides

values observed. From the results, a systematic approach for the interpretation of the DART mass spectra of organic disulfides was developed and successfully applied to various disulfide compound classes (e.g., aryl, alkyl, benzyl, and phenyl). Organic solvents were also observed to influence the ability to detect the compounds. Benzene; dichloromethane; hexane; and with some exceptions, ethyl acetate and tetrahydrofuran were found to be suitable, while disulfide signals in dimethylformamide were totally absent.
