Matrix-isolation photochemistry (λ > 299 nm; Ar, 10 K) of 5-cyano-2H-pyran-2-one (5, δ-cyano-α-pyrone) shows complete conversion to a mixture of several ring-opened ketene isomers (6) and a ring-closed Dewar lactone (7), as detected by infrared sp

Online poster sessions provide the benefits of typical face-to-face poster sessions while eliminating some of the obstacles such a nontraditional assessment presents. It allows students to do in-depth research on a specific topic and then present the

The effects of cyano substitution on cyclobutadiene are explored using density functional, coupled-cluster, CASSCF, and CASPT2 calculations. An isodesmic reaction is employed to gauge the relative stabilization (DeltaH(rxn) degrees) of cyclobutadiene

The absorbance and fluorescence of 2-(1-pyrrolyl)-pyridine and three methylated derivatives have been studied in a variety of solvents. Absorbance spectra of the molecules were found to exhibit minor solvent dependence. The fluorescence spectra for a

In support of a deeper understanding of the chemistry of cyanoacetylene--a known constituent of planetary atmospheres and interstellar space--theoretical and experimental studies address the chemical mechanism of dimerization and trimerization, and p
