Abstract

Chemistry

General and physical chemistry

Exact sciences and technology

The light-induced Ni–C to Ni–L transition results in the dissociation of a hydrogenic species, originating from the dihydrogen splitting at the active site. Back conversion in the dark to form Ni–C was investigated by studying the rebinding kinetics of this ligand in protonated (H2/H2O) and deuterated (D2/D2O) samples using time resolved FTIR spectroscopy.
