RELATIONSHIP BETWEEN THE CONSTANTS OF GEMINAL SPIN-SPIN COUPLING OF PHOSPHORUS AND HYDROGEN ATOMS AND THE CHANGES IN THE CHROMOPHORE LINK IN AZOLOOXAPHOSPHOLENES AND THEIR PROTONATION PRODUCTS

Article abstract of DOI:10.1007/BF00519813

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.
