Friedrich Hund Book order

Friedrich Hund was a German physicist whose work profoundly advanced quantum theory, particularly concerning atomic structure and molecular spectra. His seminal contributions include Hund's rules, which govern electron configurations, and the discovery of quantum tunneling. The impact of his research on molecular orbital theory was so significant that it's sometimes referred to as the Hund-Mulliken molecular orbital theory. His expertise and investigative approach established him as a pivotal figure in 20th-century physics.
