In the following, the method obtained including only the first three terms of Equation will be referred to as CBS+CV, whereas the method including all the terms of Equation will be referred to as Best. While straightforward generalizations of Equation 4 would allow geometry optimizations at the CBS+CV and Best level, this route has not been pursued here due to the negligible improvement over junChS-F12 in the former case and to the lack of analytical gradient implementations for fT and pQ contributions in the latter case.
