Abstract
The pH-dependent (13)C chemical shifts indicate an approximately 1:1 ratio of the 3-OH:4-OH tautomeric forms of singly dissociated 3,4-dihydroxyphenylacetic acid. It is found that the (13)C chemical-shift method is an effective technique for determining tautomeric forms from pK values.Entities:
