| Summary: | Pathways of the multiphoton dissociative ionization of methanol have been investigated using TOF mass spectroscopy in moderate intense laser fields at the wavelength of 400 and 800
nm.
Dissociative ionization of methanol induced by ultrashort laser pulses has been studied at wavelengths of 400
nm and 800
nm with moderate intensity (10

W/cm
2). 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 CH
