An important problem in theoretical chemistry is the calculation of reaction rates. This is challenging because most interesting chemical reactions occur much slower than the vibrational period of atoms. Even though it is in principle possible to directly simulate the classical dynamics of atomic systems, reactions of interest ...

The solution-phase reaction dynamics of chlorine dioxide (OClO) are studied using time-resolved resonance Raman (TRRR) and femtosecond pump-probe (FPP) spectroscopy. OClO photochemistry is investigated in a variety of solvents in order to ascertain the influence of environment on the photoreactivity of this compound. Specifically, ...

The use of sonoluminescence for quantitative analysis is demonstrated with possible applications for on-line process measurement. When acoustic energy of sufficiently high intensity is applied to a liquid, microscopic bubbles are generated at weak points in the liquid. These bubbles oscillate non-linearly in the acoustic ...
