Each CSF is a linear combination of Slater determinants. Slater
Each CSF $\psi_I$ is a linear combination of Slater determinants. Slater
determinants are stored in the =determinant= section. In this group
we store the CI coefficients in the basis of CSFs, and the
matrix $\langle D_I | \psi_J \rangle$ needed to project the CSFs in
the basis of Slater determinants.

* Excited states (state group)
This group contains information about excited state. Since TREXIO version 2.3.0
the state-specific data (e.g. CI/CSF coeffcients, RDMs) is written in a separate
file in order to avoid over-complicated internal logics and global state switches.
This group contains information about excited states. Since only a
single state can be stored in a TREXIO file, it is possible to store
in the main TREXIO file the names of auxiliary files containing the
information of the other states.
The ~file_name~ and ~label~ arrays have to be written only for the master file,
e.g. the one containing the ground state wave function.
The ~id~ and ~current_label~ attributes have to be specified for each file
(containing both ground and excited state data).
The ~file_name~ and ~label~ arrays have to be written only for the
main file, e.g. the one containing the ground state wave function
together with the basis set parameters, molecular orbitals,
integrals, etc.
The ~id~ and ~current_label~ attributes need to be specified for each file.
