    Isotope Effects in Chemistry and Biology edited by Amnon Kohen. Isotope Effects in Chemistry and Biology covers current principles, methods, and a broad range of applications of isotope effects in the physical, biological, and environmental sciences.. Features: Introduces biological and environmental applications such as examination of enzyme mechanisms and hydrogen tunneling. This book covers all aspects of the chemical behaviour of the muon - a rare, short-lived, elementary particle having a mass intermediate between that of the proton and the electron. Muons provide an exceptional opportunity to investigate basic chemical interactions, simply because they are so short-lived: they can thus be studied using the powerful technique of muon spin rotation, in which the.

Isotope Biogeochemistry addresses the application of isotopes of constituents that are dissolved in the water or are carried in the gas phase. Isotopes commonly used in solute isotope bio chemistry research include the isotopes of: sulfur (Chapter 15), nitrogen (Chapter 16), and carbon (Chapters 17 and 18).

Carbon kinetic isotope effects in the gas-phase reactions of aromatic hydrocarbons wih the OH radical at ± 4 K Article (PDF Available) in Geophysical Research Letters 31(15) August In physical organic chemistry, a kinetic isotope effect (KIE) is the change in the reaction rate of a chemical reaction when one of the atoms in the reactants is replaced by one of its isotopes.

[3] Formally, it is the ratio of rate constants for the reactions involving the light (k L) and the heavy (k H) isotopically substituted reactants (isotopologues). The stable-carbon kinetic isotope effects (KIEs) for the gas-phase reactions of isoprene, methacrolein (MACR), and methyl vinyl ketone (MVK) with OH radicals were studied in a 25 L reaction.

The photochemistry of the diphenylketyl radical has been examined in nonpolar solutions. Transient studies using two-laser techniques yield an excited-state lifetime of ns in toluene at room temperature, while for diphenylketyl-O-d the lifetime is ns.
