| Abstract: | This paper is based on density functional theory B3LYP method. Using the molecular structure of 6 -31/＋ g（d,p） basis set on Central octanone and Central octanone molecular ion are optimized. It calculated the frequency of C8H14O ＋. Then, it analyzes C8H14O ＋ model for calculating the vibrating mode of Infrared activity. Thus it calculates the central octanone debris under the action of the femtosecond laser. Finally, it uses the methods based on density functional theory B3LYP and the molecular structure of 6 -31/＋ g（ d, p） basis set. The structure of these fragments were optimized to get A product of the dissociation under the action of the femtosecond laser. |
