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.
