Rudolph Arthur Marcus (born July 21, 1923) is a Canadian-born American chemist who received the 1992

outer-sphere electron transfer.[5][6][7] He is a professor at Caltech, Nanyang Technological University, Singapore and a member of the International Academy of Quantum Molecular Science
.

Education and early life

Marcus was born in

Cyril Hinshelwood at the University of Oxford. At McGill, Marcus took more math courses than an average chemistry student, which would later aid him in creating his theory on electron transfer.[12]

Marcus earned a

naturalized citizen
of the United States.

Career and research

After graduating, in 1946, he first worked at the

University of Illinois.[16] His approach to solving a problem is to "go full tilt."[17] Marcus moved to the California Institute of Technology in 1978.[18]

Marcus theory of electron transfer

Electron transfer is one of the simplest forms of a chemical reaction. It consists of one outer-sphere electron transfer between substances of the same atomic structure likewise to Marcus’s studies between bivalent and trivalent iron ions. Electron transfer may be one of the most basic forms of chemical reaction but without it life cannot exist. Electron transfer is used in all respiratory functions as well as photosynthesis. In the process of oxidizing food molecules, two hydrogen ions, two electrons, and an oxygen molecule react to make an exothermic reaction as well as H2O (water). Due to fact that electron transfer is such a broad, common, and essential reaction within nature, Marcus's theory has become vital within the field of chemistry.

2H+ + 2e− + 1/2 O2 → H2O + heat

A type of chemical reaction linked to his many studies of electron transfer would be the transfer of an electron between metal ions in different states of oxidation. An example of this type of chemical reaction would be one between a bivalent and a trivalent iron ion in an aqueous solution. In Marcus's time chemists were astonished at the slow rate in which this specific reaction took place. This attracted many chemists in the 1950s and is also what began Marcus's interests in electron transfer. Marcus made many studies based on the principles that were found within this chemical reaction, and through his studies was able to create his famous Marcus theory. This theory gave way to new experimental programs that contributed to all branches within chemistry.[19]

As of his 100th birthday, he is still active doing research. [20]

Honors and awards

Marcus was awarded honorary degrees from the

University of Illinois at Urbana–Champaign in 1997, the Technion – Israel Institute of Technology in 1998, the Technical University of Valencia in 1999, Northwestern University in 2000, the University of Waterloo in 2002, the Nanyang Technological University in 2010, the Tumkur University in 2012, the University of Hyderabad in 2012, and the University of Calgary in 2013. In addition, he was awarded an honorary doctorate from the University of Santiago, Chile
in 2018.

Among the awards he received before the Nobel Prize in 1992,

Ohio State's William Lloyd Evans Award in 1990, the Theodore William Richards Award (NESACS) in 1990, the Pauling Medal, the Remsen Award and the Edgar Fahs Smith Lecturer in 1991, the Golden Plate Award of the American Academy of Achievement[21] and the Hirschfelder
Prize in Theoretical Chemistry in 1993.

He also received a professorial fellowship at University College, Oxford, from 1975 to 1976.

He was elected to the

Foreign Member of the Royal Society (ForMemRS) in 1987.[1]

In 2019 he was awarded with the Fray International Sustainability award at SIPS 2019 by FLOGEN Star Outreach [23]
