Abstract : Benzyl alcohol/ammonia alpha, alpha-dimethylbenzyl alcohol/ammonia and benzyl alcohol/water cluster ion fragmentation and chemistry are studied for isolated cold clusters by means of one- and two-colors mass resolved excitation spectroscopy, nozzle/laser timing delay and deuteration experiments. Experiments lead to an identification of parent clusters for all fragment ion clusters observed. Fragmentation reactions depend on cluster size, structure, and (weakly) on the vibrational energy deposited in the ion. Specifically, for benzyl alcohol+(NH3)1 only cluster radical chemistry and dissociation take place, while for higher order clusters, the acid-base reaction rate increases and this reaction becomes a major fragmentation pathway for benzyl alcohol+(NH3).
