Position-specific Isotope Effects in Butane: New Geochemical Tracer

An international research group led by Prof. LIU Yun from IGCAS conducted quantum chemistry modeling with corrections beyond the harmonic approximation and the Born-Oppenheimer approximation to obtain accurate intramolecular and intermolecular carbon and hydrogen isotope fractionation factors for butane isomers at equilibrium.
