ResumoAbstract The tautomeric equilibria in phenol–triethylamine complexes have been quantitatively investigated. A method of calculation of thermodynamic parameters based on reproducing the temperature dependences of 13 C chemical shifts is described. The results are in agreement with UV and IR predictions for similar complexes. The chemical shifts characterizing molecular forms of the complexes depend on the type of phenol derivative.
