History
Ligand field theory was developed during the 1930s and 1940s as an alternative to crystal field theory (CFT). CFT describes certain properties of coordination complexes but is based on a model that emphasizes electrostatic interactions between ligand electrons with the d-electrons on the metal. CFT does not describe bonding. Ligand Field Theory, in a sense, combined CFT and the then-emerging molecular orbital theory.

Famous quotes containing the word history:
“In the history of the human mind, these glowing and ruddy fables precede the noonday thoughts of men, as Aurora the sun’s rays. The matutine intellect of the poet, keeping in advance of the glare of philosophy, always dwells in this auroral atmosphere.”
—Henry David Thoreau (1817–1862)
“The whole history of civilisation is strewn with creeds and institutions which were invaluable at first, and deadly afterwards.”
—Walter Bagehot (1826–1877)
“There are two great unknown forces to-day, electricity and woman, but men can reckon much better on electricity than they can on woman.”
—Josephine K. Henry, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 4, ch. 15, by Susan B. Anthony and Ida Husted Harper (1902)
