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。

Using B3LYP method to obtain the stable configuration of C5H8O+, and is used as the reference configuration. In the 6-31+G (D, P) basis set, we have used CIS method to calculate the structure of cyclopentanone ions excited state and vibration frequencies. In the fourth excited state, the vibration frequency is f=-1856.44 cm-1f=-311.471cm-1 , we analyze The main dissociation to obtain small molecule fragments of C4H8+ approach.

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. Studies on the possible way of obtain CH3+ small fragments by cyclopentanone ion. Judging from mass peak, there is ion fragments of CH3+, through the theoretical calculation, we have get that the fragments CH3+ by the dissociation products of C5H8O+ is the same to the fragmentation of the time-of-flight mass spectra excited by femtosecond laser. It can be preliminary judgment that C5H8O+ cleavage fragments may have CH3+ fragments in this vibration mode.

Our theoretical study aims to analyze the Way of Obtain C4H6O+ macro ion by C7H12O+ Excited State and gives out a result with proved and directed significance for the corresponding experiments. Using the CIS(Configuration Interaction with Single Substitute) method, we calculated the frequency of cycloheptanone ion excited state. It is the parent ion 1C-7C, 4C-5C fracture, generates C4H6O+ pieces. It mainly through the fifth excited state occur the dissociation process.

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.
