Reaction-diffusion dynamics: confrontation between theory and experiment in a microfluidic reactor

We confront, quantitatively, the theoretical description of the reaction-diffusion of a second order reaction to experiment. The reaction at work is \ca/CaGreen, and the reactor is a T-shaped microchannel, 10 $\mu$m deep, 200 $\mu$m wide, and 2 cm long. The experimental measurements are compared with the two-dimensional numerical simulation of the reaction-diffusion equations. We find good agreement between theory and experiment. From this study, one may propose a method of measurement of various quantities, such as the kinetic rate of the reaction, in conditions yet inaccessible to conventional methods

THE MICROWAVE SPECTRUM OF 3-METHYL-1-BUTENE

Author Institution: Department of Chemistry, Michigan State UniversityThe microwave spectrum of 3-methyl-1-butene has been examined in the 18-40 GHz frequency region. Transitions of comparable intensity have been observed for species with the vinyl group trans ($\theta = 0$) and gauche ($\theta \sim$ $120^{\circ}$) to the isopropyl group. Transitions have been observed in several excited states for both rotamers. The trans species shows appreciable centrifugal distortion, whereas similar transitions in the gauche species are hardly affected
