✦ Synopsis

ICR trapped ion techniques are used to examine the kinetics of proton transfer from MnH+ (formed as a fragment ion from HMn(CO)s by electron impact) to bases of varymg strength. Deprotonation is rapid with bases whose proton afflnity exceeds 196 f 3 kcal mol-* _ This value for PA (Mn) yields the homolytic bond dissoctation energy DO(Mn*-H) = 53 f 5 kc31 mol-r _
