The high RO ÿ quantum yield in GFP contrasts with the denatured protein or the isolated Cro which, like para-phenols (=-=Schulman et al., 1981-=-), do not fluoresce (Tsien, 1998; Zimmer, 2002). The x-ray data of the wild-type (wt) protein (Örmo et al., 1996; Yang et ...

The approach is based on Koopmans' theorem and provides familial correlations for the acidities of alcohols, carboxylic acids, phenols and mineral acids with calculated (MNDO, AM1 or PM3) HOMO energies of their anidoi:10.1002/poc.610080509Vladislav M. Vlasov...
For example, pentacyanophenol (pKa(MeCN) = 4.2) is one of the strongest acids among phenols, leav- ing 2,4,6-(SO2CF3)3-phenol behind by 1 pKa unit and 2,4,6-trinitrophenol by 7 pKa units in acetonitrile (MeCN). Inserting five-SO2CF3 or nitro groups into the benzene moiety proves...
The effect of metal and support acidity on the hydroconversion of dimeric aryl ethers, used as model molecules for lignin, is still under debate, both in terms of hydrogenolysis (cleavage of the ether bond) and formation of by-products (coupling of aroma
