Coriolis analysis of several high-resolution infrared bands of bicyclo[111]pentane-d₀ and -d₁

Creator:: Perry, A., Martin, M. A., Nibler, J. W., Maki, A., Weber, A., and Blake, T. A.
Abstract:: High-resolution infrared absorption spectra have been analyzed for two bicyclo[111]pentane isotopologues, C₅H₈ (-d₀) and C₅H₇D (-d₁), where in the latter the D-atom replaces a hydrogen on the C₃ symmetry axis such that the molecular symmetry is reduced from D₃ₕ to C₃ᵥ. Two (a"₂) parallel bands, v₁₇ and v₁₈, of bicyclopentane-d₀...

High-resolution infrared studies of the ν10, ν11, ν14, and ν18 levels of [1.1.1]propellane

Creator:: Kirkpatrick, Robynne, Masiello, Tony, Martin, Matthew, Nibler, Joseph W., Maki, Arthur, Weber, Alfons, and Blake, Thomas A.
Abstract:: This paper is a continuation of earlier work in which the high resolution infrared spectrum of [1.1.1]propellane was measured and its k and l structure resolved for the first time. Here we present results from an analysis of more than 16,000 transitions involving three fundamental bands v₁₀ (E' - A'₁),...

Probing structural evolution along multidimensional reaction coordinates with femtosecond stimulated Raman spectroscopy

Creator:: Frontiera, Renee R., Fang, Chong, Dasgupta, Jyotishman, and Mathies, Richard A.
Abstract:: Mapping out multidimensional potential energy surfaces has been a goal of physical chemistry for decades in the quest to both predict and control chemical reactivity. Recently a new spectroscopic approach called Femtosecond Stimulated Raman Spectroscopy or FSRS was introduced that can structurally interrogate multiple dimensions of a reactive potential energy...

Zero kinetic energy photoelectron spectroscopy of jet cooled benzo[a]pyrene from resonantly enhanced multiphoton ionization

Creator:: Zhang, Jie, Harthcock, Colin, Han, Fangyuan, and Kong, Wei
Abstract:: We report zero kinetic energy (ZEKE) photoelectron spectroscopy of benzo[a]pyrene (BaP) via resonantly enhanced multiphoton ionization (REMPI). Our analysis concentrates on the vibrational modes of the first excited state (S₁) and those of the ground cationic state (D₀). Similar to pyrene, another peri-condensed polycyclic aromatic hydrocarbon we have investigated, the...

Nonstoichiometric Intensities in Core Photoelectron Spectroscopy

Creator:: Söderstrom, J., Mårtensson, N., Travnikova, O., Patanen, M., Miron, C., Sæthre, L. J., Børve, K. J., Rehr, J. J., Kas, J. J., Vila, F. D., Thomas, T. D., and Svensson, S.
Abstract:: X-ray photoemission spectroscopy is used in a great variety of research fields; one observable is the sample's stoichiometry. The stoichiometry can be deduced based on the expectation that the ionization cross sections for innershell orbitals are independent of the molecular composition. Here we used chlorine-substituted ethanes in the gas phase...

Excited-State Proton Transfer of Photoexcited Pyranine in Water Observed by Femtosecond Stimulated Raman Spectroscopy

Creator:: Han, Fangyuan, Liu, Weimin, and Fang, Chong
Abstract:: We use femtosecond stimulated Raman spectroscopy (FSRS) to illuminate the choreography of intermolecular excited-state proton transfer (ESPT) of photoacid pyranine (8-hydroxypyrene-1,3,6-trisulfonic acid, HPTS) in water. The multidimensional reaction coordinate responsible for photoacidity is revealed to involve sequential activation of characteristic skeletal motions during the ca. 1 ps preparation stage preceding...

Resonantly enhanced multiphoton ionization and zero kinetic energy photoelectron spectroscopy of Benzo[e]pyrene

Creator:: Harthcock, Colin, Zhang, Jie, and Kong, Wei
Abstract:: We report zero kinetic energy (ZEKE) photoelectron spectroscopy via resonantly enhanced multiphoton ionization (REMPI) for benzo[e]pyrene. Extensive vibronic coupling between the first electronically excited state and a nearby state allows b₂ symmetric modes to be observed which would normally be Franck-Condon (FC) disallowed. These vibronic modes are comparable in intensity...

Tunable sideband laser from cascaded four-wave mixing in thin glass for ultra-broadband femtosecond stimulated Raman spectroscopy

Creator:: Zhu, Liangdong, Liu, Weimin, and Fang, Chong
Abstract:: We demonstrate the generation of broadband up-converted multicolor array (BUMA) in a thin BK7 glass slide using two noncollinear weak near-IR laser pulses with various crossing angles. The BUMA signal arises from cubic nonlinear χ⁽³⁾:χ⁽³⁾ processes via cascaded four-wave mixing of the two incident beams. Broad and continuous tunability of...

Synthesis of α-Ketoester- and α-Hydroxyester-Substituted Isoindazoles via the Thermodynamic Coarctate Cyclization of Ester-Terminated Azo-Ene-Yne Systems

Creator:: McClintock, Sean P., Forster, Nathan, Herges, Rainer, and Haley, Michael M.
Abstract:: The synthesis of isoindazoles bearing α-ketoester and α-hydroxyester groups via the coarctate cyclization of ester terminated azo-ene-yne precursors is described. Whereas previous studies on isoindazole formation have shown the reaction to proceed through a kinetic coarctate pathway, functionalization of the terminal acetylene with a methyl ester sufficiently stabilizes the carbene...
