The flowing afterglow and selected-ion flow tube (SIFT) techniques have been applied in room-temperature measurements of the kinetics for proton-transfer reactions of ethane with HeH + , H 3 + , N 2 H + , CH 5 + , N 2 OH + , and HCO + . The fragmentation of C 2 H 7 + was followed over a range in excess energy of l00 kcal mol −1 . Equilibrium constants were measured at low excess energies for the proton-transfer reactions with HCO + and N 2 OH + . The latter provided values for the proton affinity of ethane and ΔH f 0 (C 2 H 7 + ) and, indirectly, values for the proton affinity of ethylene and ΔH f 0 (C 2 H 5 + ). Additional measurements of the kinetics of the reactions of C 2 H 6 with H + itself, O + , OH + , and H 2 O + provided insight into the competition between proton-transfer and other reaction channels and the fragmentation associated with the C 2 H 6 + ion.
