Template Parameters

Coeffs	the type of LCAO coefficient matrix
Energies	the type of LCAO energy vector
Occs	the type of LCAO occupancy vector

Parameters

atoms	the set of atoms (coordinates in atomic units)
cell_axes	the primitive vectors of the unit cell (in atomic units)
basis	the set of shells; must meet Molden requirements (see below)
coefficients	the matrix of LCAO coefficients (columns are LCAOs, rows are AOs; AOs are ordered according to the order of shells in basis and by the ordering conventions of this Libint configuration)
occupancies	the vector of occupancies (size = # LCAOs)
space_group	(base-0) index of the space group in the International Tables of Crystallography (https://it.iucr.org/Ac/)
energies	the vector of energies (size = # of LCAOs); the default is to assign zero to each LCAO
symmetry_labels	the vector of symmetry labels (size = # LCAOs); the default is to assign empty label to each LCAO
spincases	the vector of spin cases (size = # LCAOs; true = spin-up or m_s=1/2, false = spin-down or m_s=-1/2); the default is to assign spin-up to each LCAO
bohr_to_angstrom	the conversion factor from bohr to angstrom; the default is CODATA 2018 value

Exceptions

std::logic_error

if the basis does not conforms Molden requirements

Note

Molden can only handle basis sets that:

• p (l=1) shells are Cartesian, not solid harmonics
• d, f, and g (l=2..4) shells are all Cartesian or all solid harmonics
• there are no shells with l>5
