I have been carrying out research in theorical studies of electronically nonadiabatic chemical reactions in the gas phase, including photo-induced dissociation and collisional non-reactive quenching scattering. Now I’m using the same first-principles approaches to investigate the isotope effect in photolysis, ionization, low-temperature collision and those elementary reactions that cannot be treated by conventional Bigeleisen-Mayer  equation or Urey model, in order to shed light on the origin of non-mass-dependent fractionation. Long-term plan is to establish a theory beyond Bigeleisen-Mayer equation or Urey model which can explain and predict both mass-dependent and non-mass-dependent fractionations.
