The pK's of the -N1H- groups for the several deoxynucleic acid components have been studied as a function of temperature. From this the △Ĥ's for the ionizations are obtained. The components studied were thymidine, thymidylic acid, deoxyguanosine, and deoxyguanylic acid (5').
Atkinson, Thomas Vincent, Jr. (Thu,) studied this question.
