Abstract The present-day state as well as the history of isotope organic geochemistry is reviewed. Theoretical aspects of isotope fractionation in a system of complex organic molecules, fractionation of carbon isotopes in the biosphere, isotopes as applied to study the transformation of organic matter, geochemistry of oil and gas, evolution of the carbonate–organic carbon system and aspects of astrobiology are considered.
