## Abstract A highβspin model of nitrogenase with a Fe~8~S~9~X^+^ cluster (X = nitrogen or carbon) is used to test a mechanism for molecular hydrogen production, which is known to accompany ammonia production. The reaction proceeds with a series of protonationβreduction (PR) steps which are conside
