• Conformations of acetanilides were studied by UPS in the vapour phase. The dihedral angle, θ, between the amide group and the phenyl group was evaluated from the difference in the vertical ionization energy, <I>ΔE</I><SUB>iv</SUB>, between the two MO’s, the anti-bonding and bonding type combinations of the benzene ring e<SUB>1g</SUB>(S) orbital and the highest occupied π orbital of the amide group. The steric inhibition of conjugation due to <I>N</I>-methylation is larger than that due to ortho-methylation. For this series of compounds, <I>ΔE</I><SUB>iv</SUB> is directly proportional to cos θ and this simple relationship is useful for the rough estimation of θ.
