Robert Mulliken

Robert Mulliken was a renowned American physicist and chemist who made significant contributions to the fields of molecular physics and quantum chemistry. He is best known for his work on molecular orbital theory, which was influenced by the work of Erwin Schrödinger and Werner Heisenberg. Mulliken's research was also shaped by his interactions with other prominent scientists, including Linus Pauling and John Slater. His work had a profound impact on the development of chemical bonding theory and the understanding of molecular structure.

● Early Life and Education

Mulliken was born in Newburyport, Massachusetts and grew up in a family of modest means. He developed an interest in physics and chemistry at an early age, which was encouraged by his parents and teachers. Mulliken attended the Massachusetts Institute of Technology (MIT), where he studied chemical engineering and was influenced by the work of Arthur Amos Noyes and Richard Tolman. He later moved to the University of Chicago, where he earned his Ph.D. in physics under the supervision of Robert Andrews Millikan and Frederick Soddy.

● Career

Mulliken's career spanned several decades and was marked by appointments at various prestigious institutions, including the University of Chicago, New York University, and the Florida Institute of Technology. He was also a visiting professor at Harvard University, University of California, Berkeley, and Stanford University. Mulliken's research was supported by grants from the National Science Foundation and the American Chemical Society. He was also a fellow of the American Physical Society and the American Academy of Arts and Sciences.

● Research and Contributions

Mulliken's research focused on the development of molecular orbital theory, which was a major breakthrough in the field of quantum chemistry. He introduced the concept of molecular orbitals and developed the Hund-Mulliken method for calculating molecular energy levels. Mulliken's work was influenced by the research of Fritz London and Walter Heitler, and he collaborated with other prominent scientists, including John van Vleck and Henry Eyring. His research had a significant impact on the understanding of chemical bonding and the development of molecular spectroscopy.

● Awards and Honors

Mulliken received numerous awards and honors for his contributions to physics and chemistry. He was awarded the Nobel Prize in Chemistry in 1966 for his work on molecular orbital theory. Mulliken also received the Priestley Medal from the American Chemical Society and the Willard Gibbs Award from the Chicago Section of the American Chemical Society. He was elected a member of the National Academy of Sciences and the American Philosophical Society.

● Personal Life

Mulliken was married to Catherine Waples, and they had two children together. He was known for his love of music and hiking, and he was an avid mountain climber. Mulliken was also a talented pianist and enjoyed playing the works of Ludwig van Beethoven and Johannes Brahms. He was a member of the American Alpine Club and the Sierra Club.

● Legacy

Mulliken's legacy is profound and far-reaching. His work on molecular orbital theory has had a lasting impact on the field of quantum chemistry and has influenced the research of countless scientists, including Roald Hoffmann and K. Barry Sharpless. Mulliken's contributions to the development of chemical bonding theory have also had a significant impact on the understanding of molecular structure and chemical reactivity. He is remembered as one of the most important scientists of the 20th century, and his work continues to inspire new generations of researchers in the fields of physics, chemistry, and materials science.
