Abstract

Methyl iodide ions are prepared in the ²Π_1/2 and ²Π_3/2 spin states by multiphoton ionization. Resonant enhancement via low-lying Rydberg states is used to produce ions in a controlled, narrow distribution of vibrational levels as shown by the photoelectron spectra obtained at the selected ionization wavelengths. The photodissociation spectra of CH₃I⁺ and CD₃I⁺ are obtained in a time-of-flight mass spectrometer and analyzed to obtain the vibrational constants for X̃ and Ã states and the spin-orbit splitting of the X̃ state.
