Time and Energy Resolved Fluorescence of Cis-glyoxal
نویسنده
چکیده
A pulsed, tunable dye laser has been used to escite the O-O band of cis~glyoxal near 4875 A, at pressures from 30 to I50 mtorr, Fluorescence was resolved through a spectrometer and lifetines measured. Rate constants for the quenching of the vibrationless levels of the first excited singlet states of cisand frans.glyoxal ‘uy argon, cyclohexane and glyoxal are presented. Quenching rates of cis-glyoxal are generally two to three times faster than the corresponding rrans rates. A zero-pressure extrapolated lifetime of 0.96 2 0.02 ~.~sec is obtained for cis.glyoxal.

State-resolved dissociation dynamics of glyoxal near the threshold for formation of fragment HCO
Fluorescence excitation spectra for transition à Au – X̃ Ag of trans-glyoxal in a supersonic jet were recorded with laser excitation in a wavelength region near 395 nm. With resolution 0.04 cm, most lines in these spectra are resolved and are assigned rotationally; of six bands assigned, three have c-type rotational structure, and another three have types a/b hybrid, a and b . Fluorescence decay...
متن کاملVibrational energy redistribution in glyoxal following internal conversion
The vibrational redistribution of energy following internal conversion in glyoxal has been studied in a molecular beam using the "pump-and-probe" technique. A beam of glyoxal is initially pumped from So to a selected vibronic level of Sl. After internal conversion occurs, a tunable dye laser is used to probe the hot band absorption of the molecules by re-excitation into Sl. The total fluorescen...

Time resolved laser induced incandescence (LII) technique is used to measure size distribution of soot nanoparticles of candle's flame. Pulsed Nd:YAG laser is used to heat nanoparticles to incandescence temperature and the resulting signal is measured. Mass and energy balance equations are numerically solved to calculate temperature of soot particles in low fluence regime. Assuming Plank black ...
متن کاملDOAS measurement of glyoxal as an indicator for fast VOC chemistry in urban air
[1] We present the first direct measurements of glyoxal (CHOCHO) in the atmosphere, and demonstrate that glyoxal measurements are possible by differential optical absorption spectroscopy (DOAS). Glyoxal was routinely detected during the daytime in Mexico City, where mixing ratios ranged from <0.15 ppbv (detection limit) to 1.82 ppbv. These time-resolved measurements resolve the rapid diurnal va...
متن کاملSynthesis and X-Ray Structural Determination of 2,4,6,8- Tetraphenyl- 2,4,6,8- Tetraazabicyclo [3.3.0] Octane
Condensation of glyoxal, formaldehyde and anilines lead to the formation of 2,4,6,8- tetraphenyl and substituted phenyl 2,4,6,8-tetraazabicyclo [3.3.0] octanes. The reactions are sensitive to pH and temperature. Ortho derivatives of anilines do not participate in this condensation. X-ray structural determination reveals a cis-dienvelope geometery about the two fused rings.
