452. EUCLID: An Interactive System for Calculations
Relating to Molecular Geometries
by Hanno Essen, Department of Chemistry, McMaster University, Hamilton, Ontario, Canada L8S 4M1 The most distinctive feature of this program is its capability of calculating Cartesian coordinates from input of triples of geometric parameters (distances, angles and dihedral angles) of a quite general class. Coordinates (which may be Cartesian, cylindrical or spherical) can also be used for input or obtained as output. Geometric parameters can be obtained as output either in Z-matrix form or as lists of distances or angles. Some editing of the arrays containing nuclear positions and charges is possible. The geometric operations translation, rotation and reflexion can be performed on all or subsets of the entered nuclei. NOTE:This program is in FORTRAN 77 and uses the symbol (") as a delimiter for literal strings. It also uses the unspecified format for free field input.
