โœฆ Synopsis

Working within a time-independent framework, we demonstrate that to obtain accurate values for total pbotodissociation cross sections, one need determine the photofragment wavefunction only within the Franck-Condon region. This considerably lightens the computational overhead. The present algorithm, similar in spirit to earlier work of Singer, Lee and Freed, represents the time independent analogue of the particularly simple approach, due to Heller, which relates, in a time-dependent framework, the total photodissociation cross section to the Fourier transform of an autocorrelation function.

In this paper a new method for the determination of unsteady pressure with a tubing system is shown. The conventional methods try either to optimize the frequency behaviour of the tubing system by implementing restrictors or instantaneous jumps in the cross-sectional area or to correct the measureme
