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。

The Way

Using the CIS (Configuration Interaction with Single Substitute) method, we calculated structure of cycloheptanone ion excited state and frequency of vibration. Comparison can be seen from the table 3, the path formed by the debris path C lowest energy structure, so the stable structure of C4H5O+ fragmentation can be shown in path C. It is the parent ion 1C-7C, 4C-5C fracture formation, one of 9H and 10H migration. 11H and 12H migrated from 3C to 4C, formed C4H5O+ fragmentation. It mainly through the fifth excited state occur the dissociation process.
