✦ Synopsis

Mixed water-methanol clusters are investigated utilizing a laser based reflectron time-of-flight mass spectrometer. The intensity distributions of (H20),,(CH30H),,$I+ show magic numbers at ntm=2l,O<:m<8 due to the enhanced stabilities ofthe dodecahcdral cage structures in the mixed clusters. Studies of the metastable dissociations of (HzO),(CHsOH),H+ (n+m<40) provided evidence that the dissociation channels are governed by the competition of effects dominated by dipole-dipole and dipole-polarizability interactions compared to those arising due to the hydrogen-bonded nature of the cluster, and the cluster structure.
