For this compilation the data stored by the Radiation Chemistry Data Center bibliographic database through 1986 were processed using the SELECT keywords: purines, pyrimidines, nucleotides, nucleosides, nucleic acids and pulse radiolysis. The number of citations found was reduced by about one-third by eliminating privately published symposia papers, theses and papers not strictly relevant to this topic, e.g. on flavins, NADH, one-electron reduction of nitrouracil or the redox potential of isobarbituric acid. On the other hand, a few more papers known to us but not revealed by the keywords were added. The bibliography is arranged in approximately chronological order, references grouped by year of publication. Reviews are collected at the end of the bibliography in a separate section.
