Programs recommended for use with MOPAC

MOPAC is the core program of a series of programs for the theoretical study of chemical phenomena. This version is the sixth in an on-going development, and efforts are being made to continue its further evolution. In order to make using MOPAC easier, five other programs have also been written. Users of MOPAC are recommended to use all four programs. Efforts will be made to continue the development of these programs.
