The validity of the adiabatic-nuclear-rotation theory of electron-molecule scattering is assessed for near-threshold rotational excitation of Hz. Integrated and differential cross sections calculated using this theory are compared with those determined using the more accurate laboratory frame close-coupling theory. A recently proposed energy-modified adiabatic theory is tested and shown to lead to marked improvement in the approximate integrated (but not differential) cross sections.
