Exact Asymptotic Relaxation of Pseudo-First-Order Reversible Reactions

Physical Review Letters, 1997
The relaxation kinetics of the diffusion-influenced reversible reaction $A+B\ensuremath{\rightleftharpoons}C$ is studied in the pseudo-first-order limit $([B]\ensuremath{\gg}[A])$ when A and C are static and the B's move independently with diffusion coefficient D. For the initial condition $[A(0)]\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1$, $[

The pseudo-first-order Stark effect and the orientation of HXeI molecules

Journal of Modern Optics, 2003
We show that the gas-phase HXeI molecules can be strongly oriented via a pseudo-first-order Stark effect. This occurs owing to combined electrostatic and non-resonant laser fields acting synergically on the induced and permanent dipole moments of the molecule.

Spectrochemical evaluation of first order and pseudo-first order reactions following charge transfer for chronoamperometry at transparent electrodes

Journal of Electroanalytical Chemistry, 1970
Summary Relationships for spectrochemical evaluation of first-order and pseudo-first-order reactions following reversible electron transfer have been developed for chronoamperometry at optically transparent electrodes. Computer generated curves for the time dependent absorbance are presented for the general case where both electro-chemical and ...

Pseudo - first - order phase transitions in one dimension

Physical Review A, 1974
The effect of fluctuations on a Landau-Ginzburg model of a first-order phase transition in one dimension is studied. Extremely sharp pseudotransitions can be obtained. The critical region or width of the transition is found to vanish exponentially with the effective number of interacting units across a cross section of the system.

First-order and pseudo-first-order elimination kinetics

Science of The Total Environment, 1991
There is evidence that, for a number of chemicals, the elimination characteristics during bioconcentration do not follow monophasic first-order kinetics. In the first part of the present communication, a simple mathematical formula is presented that allows a clear-cut distinction between monophasic (pseudo-) and first-order and morephasic or higher ...

Determination of Eukaryotic Peptidyltransferase Activity by Pseudo-First-Order Kinetic Analysis

Analytical Biochemistry, 1997
We have developed an in vitro system for the determination of peptidyltransferase activity in rabbit reticulocyte ribosomes. Using this system, a detailed kinetic analysis of a model reaction for peptidyltransferase is described, with AcPhe-tRNA as the peptidyl donor and puromycin as the acceptor.
