Intracluster hydrogen transfer followed by dissociation in the phenol–(NH3)3 excited state: PhOH(S1)–(NH3)3→PhO•+(NH4)(NH3)2

Abstract
The study of the phenol– ( NH 3 ) 3 cluster with two-color two-photonionization shows that the main ion observed with delays between the lasers up to a few hundred nanoseconds is the ( NH 4 ) + ( NH 3 ) 2 fragment, resulting from direct ionization of the ( NH 4 )( NH 3 ) 2 product coming from the reaction: PhOH (S 1 )– (NH 3 ) 3 → PhO • +(NH 4 )(NH 3 ) 2 .
