Photofragmentation of (CO2)+n: Simple energy dependence for the number of neutrals ejected, 13<n<26

Abstract

Ionic photofragmentation patterns of (CO₂)⁺_n, 2<n2 molecules lost increases smoothly with cluster size, approaching a constant value that depends linearly on the photon energy. A model for involving sequential loss of CO₂ monomers is indicated, and the average CO₂‐cluster bond energy is found to be constant at 4.9 kcal/mol for n>13.
