# I. A computer program for generation of a complete set of coordinates and force matrices for normal mode calculations of crystals and molecules

## Description

Title of program: FYCOOR Catalogue Id: ACXQ_v1_0 Nature of problem In this paper a computer code, FYCOOR, is described for generation of a complete set of coordinates to be used in a normal mode calculation for crystals or for molecules. This program eliminates or reduces time- consuming and error producing complexities, which have handicapped the application of some computer programs for calculating normal modes.
