! EXAM32.
! Test of Coupled-Cluster energy for HNO
! The basis set used is 6-31G(d,p), with 35 AOs.
! An advanced non-iterative triples energy is
! computed, which should be better than CCSD(T).
! The two chemical core orbitals are not correlated.
!
! RHF FINAL E= -129.7891059395 after 13 iters
! Highest level result is E(CR-CC(2,3))= -130.1517479953
!
! Other results are
! 19 CCSD iterations needed to converge T1 and T2.
! E(MBPT(2)) = -130.1278985212, aka MP2 energy
! E(CCSD) = -130.1398314377
! The T1 diagnostic is 0.01448788, and the largest T2
! amplitude is for the pi->pi* double, namely -0.146352.
! It takes 15 iterations to converge the left eigen-
! state (lambda equation). A number of other
! "completely renormalized" energies are computed, with
! CR-CCL aka CR-CC(2,3),D being considered the best.
! The CCSD level dipole is 1.658371 Debye
!
! The "standard" E(CCSD(T)) is not computed by this run,
! change to CCTYP=CCSD(T) to see that.
