WebFeb 27, 2024 · Molecule Specifications. This input section specifies the nuclear positions and the number of electrons of α- and β-spin. There are several ways in which the nuclear configuration can be specified: as a Z-matrix, as Cartesian coordinates, or as a mixture of the two (note that Cartesian coordinates are just a special case of the Z-matrix).

Web1) Charge Derivation for Non-standard residues. The AMBER force fields are built around the concept of accurate pair-wise charges. The underlying unit of charge is in the form of a residue such as an Amino acid. In AMBER each residue is constrained to have a unit charge (with the exception of certain DNA and RNA terminal residues). http://www.ub.edu/bl/2024/03/16/small-molecule-dihedrals-parametrization/ dwg a eps
