Abstract：Our theoretical study aims to analyze ionization and dissociation mechanism of cyclopentanone in the excited states and gives out a result with proved and directed significance for the corresponding experiments. Using the CIS（Configuration Interaction with Single Substitute） method, and 6-31+G (d, p) basis set, we calculated the frequency of excited state of cyclopentanone ion molecule. We have investigated the different vibration patterns of C-C bond and C-H bond under different excited states with imaginary frequency. Five dissociation channels have been obtained. Generally, the possible dissociation fragments in the excited state。
