Orbitaltype

Orbitaltype is a label used in some scientific contexts to designate the category or class of an orbital. It appears in fields such as quantum chemistry, atomic physics, and celestial mechanics, where orbitals are grouped by shared properties to aid analysis, data organization, or modeling. The exact meaning of orbitaltype can vary by discipline, dataset, or software, but it generally points to the fundamental nature of the orbital being considered.

In atomic and molecular contexts, orbitaltype commonly refers to the angular characteristics and symmetry of an orbital. For atomic orbitals, traditional types include s, p, d, f, and so on, corresponding to increasingly complex angular momentum and nodal structures. In molecular systems, orbitaltype may indicate symmetry labels such as sigma (σ) or pi (π) that describe how the orbital overlaps and bonds with other atoms. Some datasets also use orbitaltype to distinguish between occupied and virtual orbitals, or to annotate spin and energy characteristics.

In celestial mechanics and astro-dynamics, orbitaltype can describe the qualitative shape or trajectory class of an orbit, such as circular, elliptical, parabolic, or hyperbolic. In practice, orbitaltype is often a metadata field used to filter and compare orbital properties within larger catalogs, simulations, or analytical tools.

Usage notes: because orbitaltype is not a universally standardized term, its precise definition depends on the source. When encountering orbitaltype, it is advisable to consult accompanying documentation or metadata to understand the specific categories and subtypes used in that context.
