It has been revealed from our recent studies that ultrafast hydrogen migration proceeds in hydrocarbon molecules when they are irradiated with ultrashort intense laser pulses . In the present study, hydrogen migration processes of methylamine induced by few-cycle intense near-infrared pulses were investigated by the coincidence momentum imaging (CMI) method. By the analysis of the released kinetic energy distributions of the Coulomb explosion pathways, we found that there are two peaks in the angle-resolved released kinetic energy distribution in the hydrogen migration pathway, indicating that two different electronic states are involved both in the hydrogen migration and the non-migration pathways.
