oqp.interop
Single public surface for MRSF excited-state analysis & interoperability.
One place to import from; the implementation lives in :mod:`oqp.analysis`,
:mod:`oqp.export`, and the in-tree :mod:`oqp.quantum` (FCIDUMP / second-quantized
Hamiltonian)::
from oqp.interop import (
MRSFExcitedStates, nto_excitation, attachment_detachment, # analysis
CubeExporter, to_qcschema, # export
dump_fcidump, from_openqp, # FCIDUMP (oqp.quantum)
parse_output, parse_pyscf_tddft, compare_results, # external diff
)
