WebIn a relaxed scan, a geometry optimisation is performed in each scan step, relaxing the geometry (all other coordinates) but keeping the constraint in place. In an unrelaxed scan, there is no optimisation performed in a scan step and hence no relaxation (much cheaper). Keep in mind when defining constraints that ORCA counts atoms from no. 0 ...
