Carbene radicals, in which the carbene is bonded to an open-shell metal with the carbene carbon possessing a radical character. Carbene radicals have features of both Fischer and Schrock carbenes, but are typically long-lived reaction intermediates. The "second generation" of the Grubbs catalysts for alkene metathesis features an NHC ligand.
Répertoire International de Littérature Musicale (International Repertory of Music Literature; Internationales Repertorium der Musikliteratur), commonly known by its acronym RILM, is a nonprofit organization that offers digital collections and advanced tools for locating research on all topics related to music.

Examples include (CO) 5 W=COMePh and (OC) 5 Cr=C(NR 2)Ph. Orbital interaction in a Fisher carbene. The carbene electrons are donated to a sigma bond, and weak pi-backbonding occurs. Fisher carbene complexes are related to the singlet form of carbenes, where both electrons occupy the same sp 2 orbital at the carbon. This lone pair donates to a ...
Entitled Directory of Music Research Libraries, RISM series C lists in five volumes all the music libraries, archives, and private collections which house historical musical materials. Each institution described in Series C has a library siglum, which is an abbreviation to identify the institution where musical sources are located.
Since that time the Bibliography of Music Literature has been a regular publication of the Staatliches Institut für Musikforschung. The last volume in print format was published in 2001 and covered the year 1988 (Frankfurt am Main: Hofmeister , 1954-1968 [volumes 1.1950/51 to 6.1960], Mainz: Schott , 1969-2001 [volumes 1961 to 1988]).
It has helped provide recordings of many of the most important and more recent pieces in the wind band literature. The recording project continues today, having followed Corporon to the University of North Texas. The project continues to this day under the label GIA Publications. Corporon's recordings exist in the form of the Teaching Music ...
Bonding scheme of carbene radical complexes as compared to Schrock and Fischer-type carbene complexes. Carbene radicals are a special class of organometallic carbenes.The carbene radical can be formed by one-electron reduction of Fischer-type carbenes using an external reducing agent, or directly upon carbene formation at an open-shell transition metal complex (in particular low-spin cobalt(II ...
