However, the db-MBE is not restricted to DFT calculations. Both the energies used for the underlying eb-MBE and the electron densities used in the db-MBE can be obtained from any quantum-chemical method. Here, we combine the db-MBE with quantum-chemical calculations using CCSD(T). We present a flexible implementation that is able to import the relevant electron densities from various quantum-chemical program packages, and we assess the accuracy of the coupled-cluster db-MBE for neutral as well as protonated and deprotonated water clusters.
