This common block contains information about the distribution of molecular orbitals among the various symmetry species. The lengths of both alpha alpha and beta beta virtual-virtual vectors which are overall totally symmetric . All variables are integers. Used in post-SCF programs only. This common block contains some rudimentary information which pertains to molecular symmetry.
All variables are integers.
Used in post-SCF programs only. This common block contains information which is extremely useful in the coding of contractions. The meaning of the variables is slightly complicated, but worth learning if any serious coding is being planned. Use of these variables is perhaps most easily learned by studying pieces of the ACES II source code, particularly programs such as vcc.f, lambda.f and dens.f. The variable ID is not used.
