Abstract

Available data regarding acid dissociation constants and UV, ¹H NMR, and ¹³C NMR spectra of all the five positional iso-mers (2-6) of N^X-methyladenine, 10 known isomers (7-16) of N^x,N^y-dimethyladenine, nine known isomers (17-25) of N^x,N^y,N^z-trimethyladenine, and five known isomers (26-30) of tetra-N-methylated adenine are tabulated for convenience of ready comparison, with 117 reference citations.
