WebIn natural systems, kinetic fractionation leads to a substrate 13C enrichment. This follows a linear function with the logarithm of the fraction of the remaining initial substrate according to a Rayleigh distillation (Mariotti et al., 1981). Secondly, preferential substrate decomposition of substances with different isotopic com- Webwhere c is the sample concentration, θ is the detection angle, R θ is the Rayleigh ratio used to characterize the intensity ratio between the scattered light and the incident light at angle θ, Mw is the sample’s weight-average molecular weight, A 2 is the second virial coefficient, and K is a constant related to (dn/dc) 2. During molecular weight measurements, …
