| Abstract: | The time of flight mass spectra of acetone and propanal at 532 um were obtained using Multiphoton ionization Time-Of-Flight Mass Spectrometric technique. We measured the percentage of fragment ions to the total ion current and dependence on laser intensity of the two molecules. Based on our experimental results, the Multiphoton ionization- Fragmentation (MPIF) mechanics of acetone and propanal was discussed. we also analyzed some formation channels of the small fragment canons, i.e. H , C , CH , and CH2 , etc. |
