Dlpno−ccsd t
WebA set of 35 representative neutral and charged tetrel complexes was investigated with the objective of finding the factors that influence the strength of tetrel bonding involving single bonded C, Si, and Ge donors and double bonded C or Si donors. For the first time, we introduced an intrinsic bond strength measure for tetrel bonding, derived from calculated … WebThere are different ways of doing a CCSD(T) calculation on an open-shell system. One could do the CCSD(T) calculation directly on an UHF determinant (UHF-UCCSD(T) ), this is the default for canonical CCSD(T) but may not be the most accurate one due to spin …
