WebSep 20, 2024 · The new strategy enables treatment of chemically relevant regions of large biological molecules through usual methods of quantum chemistry while describing the remaining parts of the systems by means of frozen extremely localized molecular orbitals transferred from properly constructed libraries. WebTherefore, this approach is sometimes denoted as “mechanical” embedding. Another type of the embedding scheme focuses only on the long-range electrostatic effect of the environment on the wavefunction of the cluster. This can be considered as a special case of the additive scheme .
