Raphael David Levine
Raphael David Levine (; born March 29, 1938) is an Israeli chemist who is a professor at the Hebrew University of Jerusalem, and the Department of Chemistry and Biochemistry, University of California, Los Angeles and the Crump Institute for Molecular Imaging of the David Geffen School of Medicine at UCLA. Biography Raphael David Levine was born on March 29, 1938, in Alexandria, Egypt. Academic career He is the Max Born professor of Natural Philosophy at the Hebrew University of Jerusalem and a distinguished professor at the University of California, Los Angeles. He is known for his contributions in the modern theory of chemically reactive collisions and unimolecular reactions. He has played a major role in the application of the principles of quantum mechanics to the description of physical change in a reaction from a microscopic point of view, introducing many new concepts and terms which became standard to this area. His major works include the quantum theory of absolute rate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Unimolecular Reaction
In chemistry, molecularity is the number of molecules that come together to react in an elementary (single-step) reactionAtkins, P.; de Paula, J. Physical Chemistry. Oxford University Press, 2014 and is equal to the sum of stoichiometric coefficients of reactants in the elementary reaction with effective collision ( sufficient energy) and correct orientation. Depending on how many molecules come together, a reaction can be unimolecular, bimolecular or even trimolecular. The kinetic order of any elementary reaction or reaction step is ''equal'' to its molecularity, and the rate equation of an elementary reaction can therefore be determined by inspection, from the molecularity. The kinetic order of a complex (multistep) reaction, however, is not necessarily equal to the number of molecules involved. The concept of molecularity is only useful to describe elementary reactions or steps. Unimolecular reactions In a unimolecular reaction, a single molecule rearranges atoms, forming ...

List Of Israel Prize Recipients
This is an incomplete list of recipients of the Israel Prize from the inception of the Prize in 1953 - 2025. List For each year, the recipients are, in most instances, listed in the order in which they appear on the official Israel Prize website. Note: The table can be sorted chronologically (default), alphabetically or by field utilizing the icon. In 1993, Yeshayahu Leibowitz was selected for the Israel Prize for "his life's work and special contribution to the society and the state," but after backlash from Prime Minister Yitzhak Rabin on political grounds, Leibowitz refused the prize in order to avoid "caus[ing a] tangle for the prime minister."
