Isotopically Modified Compounds

R-8.0 Introduction

This section describes a general system of nomenclature for organic compounds whose isotopic nuclide composition deviates from that occurring in nature. Comparative examples of the application of these rules are given in Table 18. Additional details may be found in Section H in the 1979 edition of the IUPAC Nomenclature of Organic Chemistry.

There is one other general system in use for describing isotopically modified compounds. It is based on an extension of the principles proposed by Boughton for designating compounds containing hydrogen isotopes and is currently in use mainly in the Chemical Abstract Service index nomenclature system .

The system codified in these recommendations provides for recognition of various types of isotopic modification and thus was chosen in preference to the system based on the Boughton principles.
