Data on the linear dependence of the constants of geminal spin-spin coupling of the phosphorus and hydrogen atoms on the long-wave absorption maxima in the electronic spectra for azolo[4,5-d]oxaphospholenes and their acyclic isomeric salts were obtained. The effect of the substituents and conformational factors on the indicated dependence was studied.
