Since the cost of the electronic structure computations is reduced by several orders of magnitude when using CCSD ( T ) - F12 / aug - cc - pVTZ compared to CCSD ( T ) / CBS methodology , this approach can be recommended as an alternative for generation of PESs of molecular clusters and for the interpretation of accurate scattering experiments as well as for a wide production of collisional data to be included in astrophysical and atmospherical models .
