The Study of Multiphoton Ionization Mass Spectra of Ethylamine and Dimethylamine

we report multiphoton ionization investigation for ethylamine and dimethylamine isomers at 425—455nm laser wavelength region with a supersonic molecular beam. The multiphoton ionization mass spectra are compared with the electron impact mass spectra and the feature of the multiphoton ionization mass spectra of these two isomers are discussed briefly.
