 the results of quantum chemistry calculations. By default, ARC instructs the statmech programs to compute rate
 coefficients in the modified three-parameter Arrhenius equation format:
 
-  .. math :: k(T) = A \left( \frac{T}{T_0} \right)^n \exp \left( -\frac{E_a}{RT} \right)

 Alternatively, the user may request to compute the rate coefficients in the classical two-parameter Arrhenius format:
 
-  .. math :: k(T) = A \exp \left( -\frac{E_a}{RT} \right)
