Electronic structure and global options¶

Source: gateway project 17, engine 1.3.1, commit 05361a3cc99fbad3da557084e41e21e690e5a27e. This parser reference is pinned to source version 1.3.1; it does not expand the capabilities of an installed 1.3.0 engine.

Choose method, functional and basis in the slash route. Geometry and charge are globals. Active-space and correlation controls use their generic exact calls. A schema entry, including tight-binding entries, does not establish distributed or qualified method support; consult the support matrix for the selected release.

Choose the physical model¶

Canonical request	Meaning and constraint
`hf/sto-3g`	HF with STO-3G; omitted primary calculation means energy.
`dft/pbe0/def2-svp`	Functional between model and basis; the internal SCF method remains `hf`.
`mp2(reference=uhf)/sto-3g`	MP2 with an explicitly selected UHF reference. Reference support is method dependent.
`mrsf(nstate=3)/bhhlyp/sto-3g`	Three response roots; use physical labels for a derivative or optimization.

geom="water.xyz" supplies geometry relative to the input file. Inline coordinates use a quoted multiline block. charge=0 is the integer total charge in electron-charge units. mult=1 is the ordinary HF/DFT reference multiplicity (2S+1); MRSF selects its reference automatically. Specify the basis once in the route; a second basis=... must agree.

Minimal canonical input¶

hf/sto-3g scf(conv=1e-8)
geom="H 0 0 0\nH 0 0 0.74"

The geometry is in angstrom. This H2 deck is a parser example, not a reference energy. Additional correlated and active-space schema entries below require the selected release's support matrix; parser vocabulary alone is insufficient.

Exact-source keyword appendix¶

Scientific references¶

HF and DFT; Functionals; Multiconfigurational methods.

Source chain: canonical lowering → schema conversion → calculation validation → consumer entry point. Consumer links locate the relevant subsystem; they do not prove every listed key is read or executed.
