Non-invertibility of Multiple-Scattered QELSS Spectra
George D. J. Phillies
We consider the spectrum S(q,t) and field correlation function f(q,t) of light quasielastically scattered from diffusing optical probes in complex viscoelastic fluids. Relationship…
Interpretation of Diffusing Wave Spectra in Nontrivial Systems
George D. J. Phillies
Mathematical methods previously used (Phillies, J. Chem. Phys., 122 224905 (2005)) to interpret quasielastic light scattering spectroscopy (QELSS) spectra are here applied to relat…
Enhanced Septahedral Ordering in Cold Lennard-Jones Fluids
Paul C. Whitford, George D. J. Phillies
We report molecular dynamics calculations on two-component, cold (1.2 > T > 0.56 in natural units), three-dimensional Lennard-Jones fluids. Our system was small (7813 A, 7812 B par…
Interpretation of Light Scattering Spectra in Terms of Particle Displacements
George D. J. Phillies
Quasi-elastic light scattering spectroscopy of dilute solutions of diffusing mesoscopic probe particles is regularly used to examine the dynamics of the fluid through which the pro…
