VUV spectroscopy of CH3Cl and CH3I

High-resolution photoabsorption spectra of CH3Cl and CH3I are reported in the energy range 3.9-10.8 eV (320-115 nm). Several features are observed for the first time in the CH3Cl spectrum and a number of new assignments are proposed. For both molecules, the present work provides the most reliable absolute cross-sections yet reported at energies above the dissociative A band transition.
