Ideas and perspectives: the same carbon behaves like different elements – an insight into position-specific isotope distributions [PDF]
Biogeosciences, 2020 It is expected that information on the source, reaction pathway, and reaction kinetics of an organic compound can be obtained from its position-specific isotope compositions or intramolecular isotope distribution (Intra-ID).

Sulfate triple-oxygen-isotope evidence confirming oceanic oxygenation 570 million years ago
Nature Communications, 2023 The largest negative inorganic carbon isotope excursion in Earth’s history, namely the Ediacaran Shuram Excursion (SE), closely followed by early animal radiation, has been widely interpreted as a consequence of oceanic oxidation.

Global modelling of H2 mixing ratios and isotopic compositions with the TM5 model [PDF]
, 2011 The isotopic composition of molecular hydrogen (H2) contains independent information for constraining the global H2 budget. To explore this, we have implemented hydrogen sources and sinks, including their isotopic composition, into the global chemistry ...
