Sažetak

The electronic absorption spectra of thirteen pyridine aromatic
amides of general formula R1-CO-NH- R2 (Ri, R2 = pyridil or
phenyl) were obtained in methanol and dioxane solution.
The band assignment is briefly discussed.
The dipole moments were measured in dioxane at 25 ± 0.1 °c
and compared with values calculated by both the S. H. M. 0. method
and vectorial model. The comparison suggests the most probable
conformation of derivatives which have the nitrogen either in the
ortho or meta position in one or both rings of the molecule.
