Differential absorptiometric pH titrations of the antimalarials chloroquine and quinacrine, employing the respective uncharged species at pH 12.5 in the reference cell, show that protolytic dissociation from the heterocyclic ring nitrogen atoms occurs over pH 6--12. This finding indicates that the s
## Abstract Semiempirical molecular orbital studies were performed on 5β²βguanosine monophosphate in its various states of base and phosphate ionization (employing the extended HΓΌckel method) and on guanosine protonated on Nβ3 and on Nβ7 (employing CNDO/2).
