Abstract: The gas-phase ion-molecule reactions of compounds of structure CH30 (CH2), SCH3, n= 1-3, have been investigated by the method of pulsed ion cyclotron resonance spectroscopy. The results show that when there is a choice of forming either a sulfur- containing ion or its oxygen analogue, the sulfur ion is formed preferentially. The major reactions that lead to sulfur-stabilized product ions are regioselective hydride abstractions ...
