Abstract

Photodissociation spectrum of MgCH3I+ is measured by using a reflectron time-of-flight mass spectrometer and a tunable UV laser. There are three bands peaking at about 27200, 29600, and 38100 cm-1, which all originate from 2P←2S transition of Mg +. In the dissociation processes, five kinds of ions, CH 3+, Mg+, I+, CH3I +, and MgI+, are observed as fragments. Photodissociation spectrum is assigned by theoretical calculations, and dissociation processes are discussed from the consideration of potential energy curves including charge transfer states along the Mg-I bond distance obtained by CIS calculation.
