Summary description: Atomic subshell / orbital-box diagrams for LaTeX, with automatic electron filling following Hund's rule and the Pauli principle
Announcement text:
`orbitals` draws the familiar "box-and-arrow" notation for atomic subshells (s, p, d, f). You give only the principal quantum number, the subshell letter and the number of electrons; the package fills the boxes automatically (one spin-up arrow per box first, then pairing), reproducing the high-spin free-atom ground state. It can draw: * a single subshell (`\suborbital`), * a row of subshells (`\electronconfig`), * a valence configuration with a noble-gas core (`\atomconfig`), * an empty transition-series template (`\transitionseries`). Every diagram can be scaled and placed inline in running text. Colours, box size, spacing and arrow shape are configurable.
This package is located at https://mirrors.ctan.org/graphics/pgf/contrib/orbitals More information is at https://ctan.org/pkg/orbitals
Thanks for the upload. For the CTAN Team Manfred Lotz CTAN is run entirely by volunteers and supported by TeX user groups. Please join a user group or donate to one, see https://ctan.org/lugs .

orbitals – Atomic subshell / orbital-box diagrams for LaTeX, with automatic electron filling following Hund's rule and the Pauli principle
orbitals draws the familiar box-and-arrow notation for atomic subshells (s, p, d, f). You give only the principal quantum number, the subshell letter and the number of electrons; the package fills the boxes automatically (one spin-up arrow per box first, then pairing), reproducing the high-spin free-atom ground state.
It can draw:
- a single subshell (suborbital)
- a row of subshells (electronconfig)
- a valence configuration with a noble-gas core (atomconfig)
- an empty transition-series template (transitionseries)
Every diagram can be scaled and placed inline in running text. Colours, box size, spacing and arrow shape are configurable.
