Slatertyyppisinä

Slatertyyppisinä is a Finnish-language term used in scientific writing to describe something that is of Slater type. The construction combines the surname Slater, as in Slater-type orbitals (STOs), with the Finnish adjective stem -tyyppinen meaning “of type.” The form Slatertyyppisinä arises in contexts where multiple items are described collectively as Slater-type. In Finnish discourse, the phrase functions as a descriptive modifier rather than as a standalone technical object.

In practice, Slatertyyppisinä appears in discussions of functions, basis sets, or models that employ Slater-type functions. Slater-type orbitals themselves are mathematical functions used to model atomic orbitals in quantum chemistry. They are characterized by exponential radial decay and a cusp at the nucleus, features that can offer a more realistic representation near the nucleus compared with Gaussian-type orbitals, though at the cost of more complex integrals.

The term Slatertyyppisinä is largely confined to Finnish-language texts and does not denote a separate category in standard English-language nomenclature. When translating or discussing in international contexts, researchers typically refer to Slater-type orbitals or Slater-type basis functions rather than the Finnish formulation. The concept remains the use of Slater-type functions to approximate atomic orbitals, contrasting with Gaussian-type functions that are more common in many computational implementations.
