WebThis class allows to fix an arbitrary number of bond lengths, angles and dihedral angles as well as linear combinations of bond lengths (‘bondcombos’). A fixed linear combination of bond lengths fulfils \(\sum_i \text{coef}_i \times \text{bond_length}_i = \text{constant}\). The defined constraints are satisfied self consistently. WebThe same applied to the dihedral of atom 3, if it, too, is defined in internal coordinates. In this example, an acetylene molecule is oriented along the "z" axis, and the second carbon atom is fixed in space at coordinates (0.0, 0.0, 1.0). This calculation is most easily set up using Cartesian rather than internal coordinates.
