Photoionization and field ionization studies of CH3I doped into the diatomics H-2, HD, D-2 and O-2 (up to a density of 1.0 x 10(21) cm(-3)) are presented. These data are used to extract the zero-kinetic-energy electron scattering length of each diatomic molecule from the density-dependent shift of the CH3I ionization energy. Scattering lengths obtained from fits of the photoionization spectra are compared to those determined from field ionization measurements.
