Combinatorial effects on clumped isotopes and their significance in biogeochemistry

A new paper from Laurence Yeung on the fundamentals of “clumped-isotope” fractionation, was recently accepted in Geochimica et Cosmochimica Acta. It shows, through simple theoretical arguments, the factors influencing the occurrence of rare-isotope pairs in molecules when they are made. One might be able to base future tracers of biogeochemistry on these principles. One of the […]
