Infrared chemiluminescence studies of the reactions of oxygen (3P) atoms with carbon disulfide and carbon monosulfide
The reactions of O(3P) atoms with CS2 and CS were studied by the technique of arrested relaxation infrared chemiluminescence. Emissions from the products CS, SO, and CO were observed from the reaction...

Possible rotational state effects in He–HD total scattering cross sections
Total scattering cross sections for 4He–HD, D2–4He, and D2–3He are reported for relative velocities between 800 and 2400 m/s. The scattering of D2–4He and D2–3He can be d...

The contribution of nuclear Overhauser enhancements to signal intensities in proton decoupled 13C nuclear magnetic resonance spectra can be determined by comparing the spectrum obtained with continuous proton irradiation to the spectrum obtained with a gated decoupler technique. The gated decoupler technique utilizes a sequence of acquiring data with the decoupler on followed by a delay time with the decoupler turned off; under appropriate conditions, it gives a fully decoupled spectrum with no nuclear Overhauser enhancements. The mathematical relationship describing the delay requirements for accurate intensity comparisons depends on the ratio of the acquisition and delay times to the longitudinal relaxation time of the carbon, as well as on the magnitude of the nuclear Overhauser enhancement.
