! EXAM01.
! 1-A-1 CH2 RHF geometry optimization using GAMESS.
!
! Although internal coordinates are used (COORD=ZMAT),
! the optimization is done in Cartesian space (NZVAR=0).
! This run uses a criterion (OPTTOL) on the gradient
! which is tighter than is normally used.
!
! This job tests the sp integral module, the RHF module,
! and the geometry optimization module.

! ROHF/GVB on Si 3-P state, using Gordon's 6-31G basis.
!
! The purpose of this example is two-fold, namely to
! show off the open shell capabilities of the GVB code,
! and to emphasize that the 6-31G basis for Si in GAMESS
! is Mark Gordon's version. The basis stored in GAMESS is
! completely optimized, whereas Pople's uses the core from
! from a 6-21G set, reoptimizing only the -31G part.
! The energy from Pople's basis would be only -288.828405.
!
! Jacobi diagonalization is intrinsically slow, but
! results in pure subspecies in degenerate p irreps.
! In fact, these may be labeled in the highest Abelian
! subgroup of the atomic point group Kh.
!
! The FINAL energy is -288.8285729745 after 7 iterations.

! ZEFF RELATIVE E= 0.0, 0.0, and +15296.859 wavenumbers.
!
! Why are there six levels? The singlet-delta is two roots,
! the singlet-sigma-plus is a third. During the CI, the
! spatial triplet-sigma-minus is one CSF, with alpha/alpha
! spin, hence IROOTS=3,1. The final spin-orbit Hamiltonian
! includes all three triplet spin states, namely adding the
! ab+ba and beta/beta triplets. So, 2+1+3=6 levels. You
! can work out for yourself these have the quantum number
! omega=0,0,1,2. Only the omega=0 states can interact,
! raising the triplet's degeneracy and slightly affecting
! the singlet-sigma-plus state's position.
!
! Note that the lower multiplicity DRT1 is done in C1
! symmetry to generate both components of the delta state.

! If you localize only the valence orbitals, by commenting
! out the $LOCAL group below, the
! Boys localization sum is 204.693589
! Ruedenberg localization sum is 5.081667
! population localization sum is 4.610528
!
! The SCF localized charge decomposition forces all MOs
! to be localized, so the final diagonal sum is 28.389125.
! The nuclear charge assigned to oxygen "lone pairs" is
! redistributed so the total nuclear P and O charges are
! correct. The energies for the PO bond, PH bonds,
! and O lone pairs are -37.273022, -27.364212, -26.363865.
! The corresponding dipoles are 2.041, 3.484, and 3.465.
!
! To analyze MP2 valence contributions, choose MPLEVL=2,
! and turn EDCOMP and DIPDCM off. The results should be
! E(MP2)=-415.4952200908, and contributions of PO bond,
! PH bonds, and O lone pairs to the correlation energy are
! -0.0442096, -0.0237793, and -0.0378790, respectively.
