The original Rayleigh equation was derived by Lord Rayleigh for the case of fractional distillation of mixed liquids. This is an exponential relation that describes the partitioning of isotopes between two reservoirs as one reservoir decreases in size. The equations can be used to describe an isotope fractionation process if: (1) material is continuously removed from a mixed system containing molecules of tw… Web1 GEO 391/376E – Environmental Isotope Geochemistry (Spring 2024) Unique Numbers ... diffusion HW1 due 4 30-Jan to 3-Feb Isotope mass balance and box modeling HW 2 5 6-Feb Rayleigh Fractionation Criss Chapter 3 section 4, pages 105-116 8-Feb Rayleigh Fractionation Criss Chapter 3 section 4, pages 105-116 10-Feb HW 2 review HW 2 due 6 …

WebRayleigh fractionation describes the evolution of a system with multiple phases in which one phase is continuously removed from the system through fractional distillation. It is used in particular to describe isotopic enrichment or depletion as material moves between reservoirs in an equilibrium process.
