Description	A selected ion flow tube study has been carried out of the reactions of H3O+, NO+ and O-2(+) with 1,2-ethanediol (ethylene glycol), 1,2- and 1,3-propanediol, 1,2-, 1,3- and 1,4-butanediol, 1,5-pentanediol, 1,2-cyclopentanediol and 2-thioethanol (or 2-mercapto-ethanol, HOCH2CH2SH). The reactions of these species with H3O+ ions are assumed to proceed via exothermic proton transfer, their rate coefficients, k(c) being equal to the calculated collisional rate coefficients, k(c). On this basis, the experimental k values for most of the NO+ and O-2(+) reactions are also close to their respective k(c) values, although the k values for three of the NO+ reactions are measurably smaller than their k(c) values. In the H3O+ reactions the protonated parent ions MH+, are always minor product ions. (MH-H2O)(+), resulting from the loss of H2O from the nascent MH+ ions being the major product ions.
