Intracluster ion-molecule reactions of the photoionized van der Waals complexes of C{sub 6}H{sub 5}F with NH{sub 3} and with H{sub 2}O have been investigated by means of two-color multiphoton ionization spectroscopy in combination with mass analysis. Two different intracluster reactions of C{sub 6}H{sub 5}F-NH{sub 3}, the substitution reaction yielding C{sub 6}H{sub 5}NH{sub 2}{sup +} and the dissociation yielding C{sub 6}H{sub 5}F{sup +}, were induced by the selective photoionization of different isomers of the complexes. Ionization threshold spectra of the complexes and appearance energies of the reaction products were observed. Energetics of the reactions was discussed on the bases of the experimental results and the calculated geometries of the isomers. It was concluded that the nucleophilic substitution reaction is responsible for the C{sub 6}H{sub 5}NH{sub 2}{sup +} production. Isomer-dependent reactions occurring within the H{sub 2}O complexes were also presented, and their energetics was discussed in relation to a barrier height to the substitution reaction.
