abstract = "A number of molecular spectroscopists are currently doing normal coordinate calculations, and several computer programs have been described. Manual preparation of the input data utilized by the program that calculates the G matrix requires little time. However, manual preparation of
the force constant matrix normally requires several hours, and it must be carefully checked because of the likelihood of making errors. A program has now been written in FORTRAN IV for the DEC-10 computer system that determines the Z matrix by examination of the G matrix and comparison of
those elements with programmed values. The G matrix must be calculated with specified bond lengths and bond angles, but if structural data show different values, a different G matrix can be used to calculate the Z matrix than the one used in the vibrational calculations.",
