Iodomethylzinc iodide is known as the Simmons-Smith reagent, after Howard E. Simmons and Ronald D. Smith of Du Pont who first described its use in the preparation of cyclopropanes. 

Fresh peppers are excellent sources of vitamins A and C, as well as neutral and acidic phenolic compounds (Howard and others 2000). Levels of these can vary by genotype and maturity and are influenced by growing conditions and processing (Mejia and others 1988 Howard and others 1994 Lee and others 1995 Daood and others 1996 Simmone and others 1997 Osuna-Garcia and others 1998 Markus and others 1999 Howard and others 2000). Peppers have been reported to be rich in the provitamin A carotenoids (3-carotene, a-carotene, and (3-cryptoxanthin (Minguez-Mosquera and Hornero-Mendez 1994 Markus and others 1999), as well as xanthophylls (Davies and others 1970 Markus and others 1999). Bell peppers have been shown to exert low antioxidant activity (Al-Saikhan and others 1995 Cao and others 1996 Vinson and others 1998) or may even act as pro-oxidants (Gazzani and others 1998). 

Photolysis aqueous photolysis tA = 67-200 d, based on measured photolysis rate constant in distilled water under midday sun at 40°N latitude (Simmons Zepp 1986 Howard 1989 Howard et al. 1991) atmospheric photolysis tA = 67-200 d, based on measured photolysis rate constant in distilled water under midday sun at 40°N latitude (Simmons Zepp 1986 quoted, Howard 1989 Howard et al. 1991) rate constant k = 2.37 x 10-3 Ir1 with H202 under photolysis at 25°C in F-l 13 solution and with HO- in the gas (Dilling et al. 1988).

At wavelengths longer than 100 nm, near the LIF transmission limit, CO appears to be completely stable with respect to dissociation in a primary step. The reactivity of optically excited CO in this region is thus due to the reactions of its excited states. Tilford and Simmons (24) have presented a set of RKR potential energy curves for CO calculated by R.H. Howard and this is given in Fig. 5 for the excited states.

Examples which come to mind are those of Philip E. Eaton, who owed his interest in cage molecules to industrial work on chlorinated pesticides, which led him to the epochal synthesis of cubane in 1964 (Traynham 1997) of Fred McLafiferty and George Olah, who both worked for a time in a laboratory of Dow Chemical of Richard E. Smalley, an industrial chemist before he enrolled as a graduate student at Princeton (Smalley 1996) of Earl Muetterties, who left the Experimental Station at DuPont in Wilmington for a professorship at the University of California of Howard E. Simmons who, when heading central research also at DuPont, turned down the offer of a professorship at Harvard (Bohning 1993, Roberts Collette 1999) and so on.

The remarkably abundant flora that exists in Lake Vanda and in the water of other lakes in southern Victoria Land defies the harsh climatic conditions of the surface. For example, the average annual temperature in Wright Valley at Lake Vanda is -19.8°C and the rate of meteoric precipitation is less than 10 mm/year. Although algae thrive in the lakes, fish and other kinds of animals with backbones have not been observed in any of the lakes in southern Victoria Land (Benoit and Hall 1970 Cameron et al. 1970 Horowitz et al. 1972 Parker and Simmons 1978 Parker et al. 1982 Love et al. 1983 Vincent and Howard-Williams 1989 Aiken etal. 1991 Simmons et al. 1993) (See also Lyons et al. 1984).
