dc.titleMolecular hydrogen ion elimination from alkyl iodides under strong laser beam irradiationen
heal.abstractThe elimination of H-2(+) from alkyl iodides under strong (up to 5 x 10(15) W cm(-2)) laser irradiation is studied by means of time-of-flight mass spectrometry. The study has been performed by using 60 fs (lambda = 800 nm) and 35 ps (lambda = 1064, 532, 355 and 266 nm) laser pulses. It is concluded that the H-2(+) ions are ejected from ionic states via Coulomb explosion processes. The molecular rearrangement leading to H-2(+) formation is attributed to a tunneling process through a H transfer barrier. For the case of methyl iodide, about 10% of the doubly charged parent ions undergo molecular rearrangement. From a comparison of the H-2(+)/H+ ion yield ratio of the studied molecules, it turns out that the H-2(+) formation from H atoms bonded to a terminal carbon atom is more efficient than that arising from H atoms bonded to central C atoms of the molecular chain.
