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 ...
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 .
The shift in the sigma bond may be antarafacial or suprafacial. In the example of a [1,5] shift in pentadiene, if there is a suprafacial shift, there is 6 e − moving suprafacially and none moving antarafacially, implying this reaction is allowed by the Woodward–Hoffmann rules. For an antarafacial shift, the reaction is not allowed.

After the game's success, the two continued to compose in the same style. In 2002, Fukui and Sekito decided to arrange some of the compositions of Nobuo Uematsu, the primary composer for the music of the Final Fantasy series. Uematsu, a fan of rock music, enjoyed these arrangements, and Fukui and Sekito asked him to join them in making a rock band.
Musical symbols are marks and symbols in musical notation that indicate various aspects of how a piece of music is to be performed. There are symbols to communicate information about many musical elements, including pitch, duration, dynamics, or articulation of musical notes; tempo, metre, form (e.g., whether sections are repeated), and details about specific playing techniques (e.g., which ...
Sheet music enables instrumental performers who are able to read music notation (a pianist, orchestral instrument players, a jazz band, etc.) or singers to perform a song or piece. Music students use sheet music to learn about different styles and genres of music. The intended purpose of an edition of sheet music affects its design and layout.
Since an anacrusis "is an incomplete measure that allows the composition [or section or phrase] to start on a beat other than one," [15] if an anacrusis is present, the first bar after the anacrusis is assigned bar number 1, and Western standards for musical notation often include the recommendation that when a piece of music begins with an ...
