Ionization of tetramethyltin, an organometallic compound, was observed when its molecular beam was injected near a metal substrate in vacuum and the laser light (the second or third harmonics of a Q-switched Nd:YAG laser) was irradiated on the surface of the metal substrate. Organometallic ions along with the substrate metal ions were observed with a quadrupole mass spectrometer. The role of a laser-irradiated metal surface in the ionization of an organometallic compound is discussed from the comparison of the appearance time (time delay necessary for an ion to be formed in or to arrive at the entrance region of the mass spectrometer after the irradiation of a laser pulse) of organometallic ions with that of substrate metal ions. The ionization of an organometallic compound by the reaction with translationally hot electrons ejected from a metal surface is concluded.
