!   EXAM45.
!   triples-corrected excited state energies by coupled cluster EOM,
!   from a closed shell ground state.
!   Molecule is CH2, with 43 AOs and 41 MOs in aug-cc-pVDZ basis.
!
!   a priori, we know that methylene has two valence excited singlet
!   states, 1-B-1 and a second 1-A-1, with the latter being a double
!   excitation from the lowest singlet 1-A-1.
!
!   reference 1-A-1: FINAL ENERGY= -38.8841290160, in 11 iters
!   reference 1-A-1:    MBPT(2) E= -38.9999600236
!   reference 1-A-1:  CCSD ENERGY= -39.0279559403, in 16 iters, T1=0.00998093
!   reference 1-A-1 lambda equation requires 7 iterations.
!   EOM-CCSD level results are
!   1-A-1: EOM-CCSD= -38.80419384, 15 iters, R2=0.7535(4**2 -> 5**2)
!   1-B-1: EOM-CCSD= -38.96328855,  7 iters, R1=0.6169(4**2 -> 4**1,5**1)
!   excited state lambda equations take 10, 7, 6 iterations.
