The structure of the CaYb+ molecule is determined and used in a calculation that explains the fast chemical reaction as a consequence of strong radiative charge transfer. A possible explanation is offered for the apparent contradiction between typical theoretical predictions and measurements of the ...
Abstract Rate constants for the reaction of O(3 P) atoms with deuterium, O+D2→OD+D, have been measured over the temperature range 825–2487 K. The experimental method that has been used is the flash photolysis–shock tube (FPST) technique. This technique utilizes atomic resonance absorption...
We do not recommend the use of 1O2 scavengers/quenchers such as sodium azide to elucidate CBBP photoreaction pathways, because the azide provides misleading results by also acting as a triplet-state quencher. Based on the experimental data, we propose a methodology for the measurement of the ...
Generally, the degree of mixing in a microchannel is calculated based on the deviation of the obtained concentration profiles from the uniform concentration using a fluorescence technique. In the present study, the luminol CL reaction is applied to estimate the local chemical reaction rate at the ...

The Measurement of the Rate Parameters for the Reactions i‐C3H7 and n‐C3H7 + HI → C3H8 + I over the Temperature Range 293–623 K: Implications for the Standard Heat of Formation of the Propyl Radicals An investigation of the absolute rate constants of the metathesis reactions i-C3H ...
Spectrophotometric rates from about 10 to 0.025 absorbance units per mm can be measured with an accuracy and precision of less than 1% relative in measurement times of about 10 to 30 s, respectively. The interface is readily constructed from commercially available components. Test results are ...
