N2 - Pyridine-2-aldehyde, 2-acetylpyridine, and α-pyridil have dipole moments of 3.35, 2.87, and 4.43 D, respectively, and molar Kerr constants of 578, 396, and -268 × 10-12. Data for the aldehyde and methyl ketone are consistent with mixtures of planar s-trans- and s-cis-conformers, with the trans-species predominating. The effective conformation of α-pyridil is a skew structure in which the dihedral angle between the C5H4N·CO planes is 80-83°; each C 5H4N·CO moiety is assumed to adopt a flat s-trans arrangement.
