Wavelength-modulation spectroscopy using a frequency-doubled current-modulated diode laser
Abstract.We have studied atomic absorption in an argon discharge by wavelength-modulation spectroscopy with a frequency-doubled diode laser. The tunable wavelength-modulated radiation at 430 nm wasExpand

The photodissociation dynamics of ozone at 193 nm: an O(1D2) angular momentum polarization study.
Polarized laser photolysis, coupled with resonantly enhanced multiphoton ionization detection of O(1D2) and velocity-map ion imaging, has been used to investigate the photodissociation dynamics ofExpand

The 193 nm photolysis of NO2: NO(ν) vibrational distribution, O(1D) quantum yield and emission from vibrationally excited NO2
Time resolved Fourier transform infrared emission has been used to study the photolysis of NO2 and its dimer N2O4 at 193 nm. NO(ν) populations from the photolysis of NO2 show a bimodal distribution,Expand

The radiative lifetime of CF(A 2Σ
Abstract The radiative lifetimes of the ν′ = 0 and 1 levels of CF(A 1Σ+) in the gas phase have been measured by observing the fluorescence decay following pulsed laser excitation. The values,Expand

Temperature dependence of CH2 (ã 1A1) removal rates by Ar, NO and H2
Absolute rate constants for the removal of CH2 (a 1A1) by Ar, NO and H2 have been measured over the temperature range 295–431 K using laser flash kinetic absorption spectroscopy. For NO and H2, noExpand

Reactions of CHF (X̃ 1A') and NCO (X̃ 2Π) Radicals
Infrared multiple photon dissociation has been used to produce ground state radicals CHF(X 1A') and NCO (X 2Π), and their kinetic behaviour in the presence of added gases studied by time resolvedExpand

Vibrational excitation of CO in the reaction: O + CS → CO + S
Abstract The relative rates at which O + CS → CO + S populates individual vibrational levels of CO have been determined (a) from infrared chemiluminescence experiments, and (b) by using a cw CO lawerExpand

Infrared chemiluminescence from the reaction O + CS → CO + S
Abstract Vibrationally excited CO is produced in the reaction sequence: O + CS2 → SO + CS; O + CS → CO + S. and gives rise to infrared emission. At least 50% of the energy of the secondary reactionExpand
