One of the important applications of chemical kinetics is the attempt to understand complex processes through kinetic modeling. This process frequently requires that rate constants be obtained by extrapolation of data either to higher or lower temperatures than the experimental, or by estimation or

โฆ Synopsis
In the ~sc when ldnetics of tunneling electron transfer are controlled predominantly by scatter in separations of donon and acceptoq the prcscnce of even large sattcr in the parameters Y ando of the corresponding rate consfant is shown not to affect markedly the shape of the kinctic~ the latter being well described by a single pair of effective parameters.

Pressure dependence of the tunneling rate for the hydrogen transfer photoreaction in acridine: fluorene was investigated at 1.4 K. Above 10 kbar, the rate rises exponentially with increasing pressure. These data constitute a measurement of tunneling rate from the vibrational ground state. Its physic
