During most molecular bonding, it is the valence electrons which principally take part in the bonding. In recognition of this fact, it is common to represent valence orbitals by more than one basis function (each of which can in turn be composed of a fixed linear combination of primitive Gaussian functions). Basis sets in which there are multiple basis functions corresponding to each valence atomic orbital are called valence double, triple, quadruple-zeta, and so on, basis sets (zet… Webemploying standard basis sets, such as the Pople style k-lmG basis sets,16 the Ahlrichs basis sets of double, triple, and quadruple quality,17 and the cc-pVXZ18 and pc-n19 families of basis sets.
