文摘

Fractionation of four stable isotopes in cocaine was investigated. An observable fractionation event occurred during precipitation of cocaine base. All four stable isotopes exhibit a fractionation opposite of the classic Rayleigh. Nitrogen and hydrogen are most affected during the observed fractionation event.
