Abstract:

The multiphoton ionization spectra of ethylamine and dimethylamine are presented in the 400-470nm region, with resonance excitation to 3s Rydberg state. The MPI fragmentation patterns of two C2H7N isomers are readily distinguished. For ethylamine, the most prevalent fragmentation is β-Cleavage, while for dimethylamine that is H atom ejection.
