Fiuorcscencc spectra and quantum yields have been determinud for n vnriety of normal and op9ic alknnes mcl for some of their alk~l dcrkativos.
In the cast of normal alkancs. the quantum yield increxes almost linenrly with number of carbon :ltoms from pcntane to heptndecane. whereas the emission spectrum rcmnins unchanged. The addition of n methyl group strongi?; reduces the qunnlum yield and shifts the spectrum to the red. For c.vclon1knne.s. a relativei!: intense emission is observed only for c~cl&e_itno znci its nlkyl dcrivntives, whereas cyciopentzmc. c>-cloheptnnc. cgclooctnne. and cyelodec-

Adamantane and 1,3,5,7-tetradeuterioadamantane were oxidized by RuO, in two solvent systems, CCI,-CH,CN-H,O and acetone-water, yielding two kinetic deuterium isotope effects (KIEs), 4.8 f 0.2 and 7.8 i 0-1, respectively, very similar to those obtained in analogous reactions with cis-decalin and perd
Coadsorption of saturated hydrocarbons and CO has been investigated by temperature-programmed desorption (TPD). Coadsorbed CO promotes the decomposition of low reactive hydrocarbons during TPD. The coverage and decomposition fraction (ratio of decomposed molecules to adsorbed ones) are determined fr
Nanosecond transient absorption studies of the lifetimes (5) of several substituted 1 ,n-diphenyl-1 ,n-diyls are reported in polar and non-polar solvents. A para-bromine substituent significantly shortens r. Substitution of OH in the l-position makes the lifetime highly solvent dependent. The substi
