code for manipulating FSRCC effective Hamiltonian eigenstates

The code is designed to perform<\p>

• finite-field transition dipole moment calculations (A.V. Zaitsevskii, L.V. Skripnikov, A.V. Kudrin, A.V. Oleinichenko, E. Eliav, A.V. Stolyarov, Optics and Spectroscopy, 124, 4, 451-456 (2018))
• quasidiabatization by projection ( A. Zaitsevskii, N.S. Mosyagin, A.V. Stolyarov, E. Eliav, Phys. Rev. A, 96, 022516 (2017))
• Pade extrapolation of effective Hamiltonians (A. Zaitsevskii, E. Eliav. Int. J. Quantum Chem. 118 (23), e25772 (2018))<\li>

It is supposed that the effective Hamiltonians are obtained using Fock space relativistic coupled cluster facility of DIRAC, a relativistic ab initio electronic structure program (release DIRAC17 or later) or EXP-T code.
