Comments:   The temperature- and pressure-dependent kinetics of unimolecular reactions of methylcyclohexane including its dissociation and isomerization channels were computed by high-level quantum chemical calculations and Rice-Ramsperger-Kassel-Marcus / master equation simulations. Arrhenius expressions for individual pressures are given in Table 2 of the article. The quoted expression is for the high pressure limit.
