Photoelectron angular distributions have been calculated, with the multiple-scattering method, for electrons ejected from the outer shells 2σ_u, 1π_u and 3σ_g of N₂ and 4σ , 1π and 5σ of CO from threshold to 10 Ryd electron kinetic energy. Clear evidence of the sigma f wave (l=3) shape resonance is seen in the 3 σ_g spectrum of N₂ and in all three spectra of CO. Agreement with very recent wavelength-dependent measurements made at the Bonn synchrotron by Marr and Holmes (1979) is generally good, but more detailed measurements and further theoretical work are needed to eliminate the remaining discrepancies.
