“…The temperature‐dependent rate constants k ( T ) are computed at temperatures of 298.15, 1000, 1500, 2000, and 2500 K using the conventional transition state theory (TST), that is, where κ is the transmission coefficient of the tunneling effect, which is calculated using the Wigner method. [ 14 ] σ is the reaction path symmetry number, σ = σ rot,R / σ rot,TST , where σ rot,R and σ rot,TST are the rotational symmetry numbers of the reactant and transition state, respectively. k B , h , and R are Boltzmann's constant, Planck's constant, and universal gas constant, respectively.…”
