Abstract :
Dissociative ionization of methanol induced by ultrashort laser pulses has been studied at wavelengths of 400 nm and 800 nm with moderate intensity (1012−13 W/cm2). The laser power dependence of ionic species shows that multi photon ionization causes an excitation with a total energy from 11 to 15 eV. Comparing the current results with those of conventional VUV photodissociation experiments, we conclude that the molecules are excited to the X, A, B and C states of the ion, resulting in the CH4O+, CH3O+, CH 3 + and CHO+ ions, respectively.
