The Fukui function is named after Kenichi Fukui, who investigated the frontier orbitals described by the function, specifically the HOMO and LUMO. [3] Fukui functions are related in part to the frontier molecular orbital theory (also known as the Fukui theory of reactivity and selection, also developed by Kenichi Fukui) which discusses how nucleophiles attack the HOMO while at the same time ...
Since the exo-product has primary (bonding) orbital interactions, it can still form; but since the endo-product forms faster, it is the major product. [2] *Note: The HOMO of ethene and the LUMO of butadiene are both symmetric, meaning the reaction between these species is allowed as well. This is referred to as the "inverse electron demand ...
Kenichi Fukui (福井 謙一, Fukui Ken'ichi, October 4, 1918 – January 9, 1998) was a Japanese chemist. [1] He became the first person of East Asian ancestry to be awarded the Nobel Prize in Chemistry when he won the 1981 prize with Roald Hoffmann , for their independent investigations into the mechanisms of chemical reactions .
Yang's main contributions to theoretical chemistry range from fundamental theory to applications of density functional theory. He (with Parr) developed the concepts of the Fukui function, [1] hardness, and softness [2] in density functional theory. He also justified the theoretical ground of potential functional (as in Optimized-Effective ...
Inside a program or a custom function, control may be conditionally transferred to a statement identified by a line number or explicit label; if the target is 0 (zero) this terminates the program or returns to a function's caller. The most common form uses the APL compression function, as in the template (condition)/target which has the effect ...
For example, the Ramanujan tau function τ(n) arises as the sequence of Fourier coefficients of the cusp form of weight 12 for the modular group, with a 1 = 1. The space of such forms has dimension 1, which means this definition is possible; and that accounts for the action of Hecke operators on the space being by scalar multiplication (Mordell ...
Fukui (Japanese: 福井) is a Japanese name meaning "fortunate" or sometimes "one who is from the Fukui prefecture". Notable people with the surname include: Kenichi Fukui (福井 謙一, 1918–1998), physical chemist who was awarded the Nobel Prize in Chemistry in 1981
"The f+ function represents the initial stage of a reaction in which the molecule of interest acts as an electrophile. The f- function, on the other hand, represents the initial stage of a reaction in which the molecule of interest acts as nucleophile." 129.82.95.87 16:12, 18 May 2023 (UTC)
