UV induced mass independent sulfur isotope fractionation in stratospheric volcanic sulfate J. Savarino, A. Romero, J. Cole-Dai, S. Bekki, and M.H. Thiemens.
Sulfur isotopes 11/14/12 Lecture outline: 1)sulfur cycle 2)biological fractionation 3)S isotopes in the geologic record 4)mass-independent S isotope fractionation.
Fig. 1.1. An extra neutron in the 13 C isotope makes the nucleus more massive or “heavier” than the 12 C isotope, but does not affect most chemistry that.
