## separability assumption

https://doi.org/10.1351/goldbook.S05611
This expression refers to the assumption, essential to conventional @[email protected], that the energy of the system may be expressed as the sum of components associated with different @[email protected] In transition-state theory it is assumed that the energy of the motion of the system through the @[email protected] of the @[email protected] is separable into various components. In many practical calculations it is assumed that the energy of the system is separable into electronic, vibrational, rotational and translational energy.
