Dimerization energies, ED, internuclear separations, R, and directionality angles have been obtained for the electron donor substituted hydrogen bonds, HO-H\*\*+OHX, X=H, CH3, NH2, OH, and F, from ab initio -molecular orbital calculations with the 4-31G basis. The internuclear separations and direct
## Abstract The ^1^H n.m.r. spectra of eleven anilides of 6βmethylβpicolinic acid __N__βoxide in chloroform were obtained. The influence of temperature, concentration and substituents on the chemical shifts of the Nο£ΏH protons was investigated. The structure of the anilides is discussed.
