Transfer integral amplitudes

Input data for the calculation were the known room-temperature structure [17] and vibrational studies of TMTSF [18]. As suggested by the structural data, the dimerization amplitude u was taken to be 0.03 A. The parameters, whose value is adjustable and determined by the fitting of the experimental data, are the transfer integral t, the gap amplitude Ak, the e-mv coupling constants g and the core dielectric constant Coo- Use of the selFconsistent relations mentioned before allows us to determine the e-p parameter (di/d u) and the percentage contribution of the static potential to the gap A. ... [Pg.134]

As for a more detailed comparison between theory and experiment, we cannot expect, of course, that all the features of the measured spectra can be accurately reproduced with a model as simple and rough as the one we have used for our calculations. For instance, in the case of (TMTSF)2C104, in order to reproduce the amplitudes of the observed vibronic structures, we have to use a gap parameter that causes the c culated conductivity maximum to be higher in frequency than the observed one. This kind of discrepancy is much less pronounced in the case of (TMTSF)2PF5, although both the gap parameter and the transfer integral are veiy similar to those of the 104" salt. [Pg.136]

Bardeen considers two separate subsystems first. The electronic states of the separated subsystems are obtained by solving the stationary Schrodinger equations. For many practical systems, those solutions are known. The rate of transferring an electron from one electrode to another is calculated using time-dependent perturbation theory. As a result, Bardeen showed that the amplitude of electron transfer, or the tunneling matrix element M, is determined by the overlap of the surface wavefunctions of the two subsystems at a separation surface (the choice of the separation surface does not affect the results appreciably). In other words, Bardeen showed that the tunneling matrix element M is determined by a surface integral on a separation surface between the two electrodes, z = zo. [Pg.22]

In addition to showing the fact that the momentum transferred to the collision partner comes from the electron, this expression also contains, in the integral over p, the Born scattering amplitude, given by Eq. (11.7). If we again replace it by the correct amplitude fe(fi, / , k - k)12 and integrate over k we find... [Pg.204]

The increase, both in lifetime and in amplitude of the slow component, reveals an increase in the chlorophyll fluorescence. The lifetime increased to 4 ns. This indicate a less efficient energy transfer from LHC-II to the PS 2 core-particle. We also calculated the yield by integrating each kinetic trace. The yield given by the measurement with the highest concentration of Triton X-100 served as a reference. We then calculated the relative yield and plotted this number against the added amount Triton X-100. This plot showed that the critical amount of Triton X-100 is about 0.015%. [Pg.1262]
