The term " orbital " was coined by Robert Mulliken in 1932.

However, the work of Friedrich Hund, Robert Mulliken, and Gerhard Herzberg showed that molecular orbital theory provided a more appropriate description of the spectroscopic, ionization and magnetic properties of molecules.

The term " orbital " was first used in English by Robert S. Mulliken as the English translation of Schrödinger's ' Eigenfunktion '.

Molecular orbitals were first introduced by Friedrich Hund and Robert S. Mulliken in 1927 and 1928.

An alternative approach was developed in 1929 by Friedrich Hund and Robert S. Mulliken, in which electrons are described by mathematical functions delocalized over an entire molecule.

Robert Sanderson Mulliken ForMemRS ( June 7, 1896 – October 31, 1986 ) was an American physicist and chemist, primarily responsible for the early development of molecular orbital theory, i. e. the elaboration of the molecular orbital method of computing the structure of molecules.

As a child, Robert Mulliken learned the name and botanical classification of plants and, in general, had an excellent, but selective, memory.
