Generation and characterization of dihydroxy disulfide, HOSSOH : the chainlike isomer of thiosulfurous acid

Dissociative ionization of diisopropoxy disulfide (C 3 H 7 OSSOC 3 H 7 ) by 70-eV electron impact gives rise to H 2 S 2 O 2 .+ ions, whose collisional activation (CA) mass spectrum is in keeping with the connectivity of HOSSOH .+ . This ion has been successfully neutralized and reionized in a two-stage collision experiment
