The Nobel Prize in Chemistry 1973 was awarded to Ernst Otto Fischer and Geoffrey Wilkinson for their pioneering work on the chemistry of the organometallic compound ferrocene called sandwich compounds
The Nobel Prize in Chemistry 1972 was awarded to Christian B. Anfinsen for his work on ribonuclease, especially concerning the connection between the amino acid sequence and the biologically active conformation and Stanford Moore and William H. Stein for their contribution to the understanding of the connection between chemical structure and catalytic activity of the active centre of the ribonuclease molecule
The Nobel Prize in Chemistry 1971was awarded to Gerhard Herzberg for his contributions in the electronic structure and geometry of molecules, i.e. free radicals
The Nobel Prize in Chemistry 1970 was awarded to Luis F. Leloir for his discovery of sugar nucleotides and their role in the biosynthesis of carbohydrates.
The Nobel Prize in Chemistry 1969 was awarded to Derek H. R. Barton and Odd Hassel for their contributions to the development of the concept of conformation and its application.
The Nobel Prize in Chemistry 1968 was awarded to Lars Onsager for the discovery of the reciprocal relations bearing his name, which are fundamental for the thermodynamics of irreversible processes. source: www.nobelprize.org
The Nobel Prize in Chemistry 1967 was awarded to Manfred Eigen, Ronald George Wreyford Norrish and George Porter for their studies of extremely fast chemical reactions, effected by disturbing the equilibrium.
The Nobel Prize in Chemistry 1966 was awarded to Robert S. Mulliken for his fundamental work on chemical bonding and the electronic structure of molecules by the molecular orbital method.
