The vapor of (chlorocarbonyl)sulfenyl bromide, ClC(O)SBr, was isolated in solid Ar, Kr, N(2), and Ar doped with 5% CO at 15 K, and the matrix was subsequently irradiated with broad-band UV--visible light (200or = lambdaor = 800 nm), the changes being

The recent isolation of fullerenes such as C{sub 60} and C{sub 70} has led to several studies of the reactivity and physical properties of their excited states. The authors recently reported that triplet C{sub 60} ({sup 3}C{sub 60}) is formed with a

The thermodynamic properties of structurally similar Mn(III) and Mn(IV) complexes have been reinvestigated to understand their reactivity with substrates having C-H bonds. The complexes have the general formula [MnH(3)buea(O)](n-), where [H(3)buea](3

Well-defined chiral fibers incorporating hydrogen-bonded oligo(p-phenylene vinylene) donor and perylene bisimide acceptor chromophores have been realized by self-assembly. Upon photoillumination of these fibers electron-transfer takes place, leading

The base hydrolysis of coordinated acrylonitrile in [ (NH₃)₅CoN=CCH=CH₂]³⁺ to the acrylamide complex in carbonate buffers obeys the rate law k(obsd) = k(OH)OH⁻] + k(c)[C0₃²⁻] (k(OH) = 35 M⁻¹ s⁻¹; k(c) = 1 M⁻¹ s⁻¹; 25 °C,
