Time-resolved experiments and calculations are reported for the predissociation dynamics of the metastable vOH=2 vibrational state of H2–OH and D2–OH in their ground electronic states. Good agreement between theory and experiment is found for the

We have constructed a cavity ring-down spectrometer employing a near-IR external cavity diode laser capable of measuring 13C/12C isotopic ratios in CO2 in human breath. The system, which has a demonstrated minimum detectable absorption loss of 3.2 x

The D and H atom products from collisional quenching of OH A 2Σ+ (v = 0) by D2 have been examined through Doppler spectroscopy using two-photon (2 2S ← ← 1 2S) laser-induced fluorescence. A bimodal Doppler profile is observed for the D atoms, in

The predissociation dynamics of ortho-H2—OH in its ground electronic state are studied in time-resolved experiments and quantum mechanical calculations. The experiments use stimulated Raman and infrared overtone pumping to excite the νH2 = 1 or ν

The hydrogen atom products of the OH A 2Σ+ (v=0)+H2→H+H2O quenching reaction have been characterized by Doppler spectroscopy. The translational energy distribution of the products is bimodal, with the two components accounting for approximately 3%

The fundamental H2 vibration of the ortho-H2–OH complex in its ground electronic state has been observed at 4151.49±0.03 cm−1 via stimulated Raman excitation. The stimulated Raman transition has been identified with an ultraviolet probe laser us

State-selective infrared excitation of o-H2–OH via the pure OH overtone transition has been used to induce a half-collision inelastic scattering event between the OH radical and ortho-H2 under restricted initial orientation conditions. The time evo

The rotationally-resolved infrared spectrum of the ground electronic state of OHH2 has been observed near the OH gn = 2 ← 0 origin by an infrared-ultraviolet fluorescence depletion technique. The experimental spectrum agrees remarkably well with
