A minimum basis set is one in which, on each atom in the molecule, a single basis function is used for each orbital in a HartreeâFock calculation on the free atom. However, for atoms such as lithium, basis functions of p type are added to the basis functions corresponding to the 1s and 2s orbitals of the free atom. For example, each atom in the second period of the periodic system (Li-Ne) would have a basis set of five functions (two s functions and three p functions).
Microsoft first released Visual Studio (codenamed Boston, for the city of the same name, thus beginning the VS codenames related to places) in 1997, bundling many of its programming tools together for the first time.
