Free positron and ortho-positronium lifetimes have been measured, along with the positronium formation fractions, for the three molecular gases H2, CO2 and CH4 in the intermediate density range. The measurements are compared with other existing data where possible and significant discrepancies between earlier results and those presented have been found. The complex behaviour observed for all three parameters has been discussed in terms of current models where applicable.
