The energy for breaking the intramolecular hydrogen bond between the phenolic OH and an aza nitrogen in two 2,4-diaryl-6-(2-hydroxy-4-methoxyphenyl)-1,3,5-triazines was determined, by dynamic 1H and 13C NMR spectroscopy, as 55 Β» 5 kJ mol-1. The activation parameters DHt and DSt for the corresponding
