Low-Frequency Vibrational Spectra of Chlorophylls a and b in Solution: Effects ofAxial Coordination
The far-infrared spectra (500--100 cm-I) of chlorophyll a were observed in three solvent systems (benzene-pyridine, benzene-tetrahydrofuran, and benzene-acetone). The observed spectra could be classified into three types corresponding to the aggregate state, the five-coordinate monomeric state, and the six-coordinate state. The far-infrared spectra of I5N_and 26lV[g-substitutedspecies and the p...
متن کاملVibrational spectra in glasses
The findings of X-ray and neutron scattering experiments on amorphous systems are interpreted within the framework of the theory of Euclidean random matrices. This allows to take into account the topological nature of the disorder, a key ingredient which strongly affects the vibrational spectra of those systems. We present a resummation scheme for a perturbative expansion in the inverse particl...
متن کاملSimple posterior frequency correction for vibrational spectra from molecular dynamics.
Vibrational spectra computed from molecular dynamics simulations with large integration time steps suffer from nonphysical frequency shifts of signals [M. Praprotnik and D. Janežič, J. Chem. Phys. 122, 174103 (2005)]. A simple posterior correction technique was developed for compensation of this behavior. It performs through replacement of abscissa in the calculated spectra using following form...
متن کاملPoisson ratio and excess low-frequency vibrational states in glasses.
In glass, starting from a dependence of the Angell's fragility on the Poisson ratio [V. N. Novikov and A. P. Sokolov, Nature 431, 961 (2004)], and a dependence of the Poisson ratio on the atomic packing density [G. N. Greaves, A. L. Greer, R. S. Lakes, and T. Rouxel, Nature Mater. 10, 823 (2011)], we propose that the heterogeneities are predominantly density fluctuations in strong glasses (lowe...
