Sir Harold W. Kroto

Born 7 Oct 1939. English chemist who shared (with Richard E. Smalley and Robert F. Curl, Jr.) the 1996 Nobel Prize for Chemistry for their joint discovery of the carbon compounds called fullerenes. These new forms of the element carbon contain 60 or more atoms arranged in closed shells. The number of carbon atoms in the shell can vary, and for this reason numerous new carbon structures have become known. Formerly, six crystalline forms of the element carbon were known, namely two kinds of graphite, two kinds of diamond, chaoit (1968) and carbon(VI) (1972). Fullerenes are formed when vaporised carbon condenses in an atmosphere of inert gas. The carbon clusters can then be analysed with mass spectrometry.
