The Biliary System: Overview

Frequency-and Temperature-Dependence of Second Refractivity Virial Coefficients

“…For the static case this has been done in a systematic way by Dacre [17][18][19][20] with ab initio SCF-CI calculations. These calculations support a relationship already found before for spherical species in the framework of dielectric virial coefficients [26] as well as collision induced absorption (CIA)-spectra [15,27], namely…”

“…In this case, / ov is assumed to be independent of the shape, although a possible anisotropic behaviour might be introduced via a shape factor. Using ab initio calculations as well as a fit to CIA-spectra and second dielectric virial coefficients, it has been shown that r t is in the order of 4 • 10" 11 m [15,27]. X x is usually obtained through fitting to existing experimental and/or theoretical data, which is also used in the present work.…”

“…These limitations are not present in theoretical calculations of B R (co, T), but in the case of the frequency-dependence of B R (co, T) a Reprint requests to Dr. U. Hohm, Institut für Physikalische und Theoretische Chemie, TU Braunschweig, Hans-Sommer-Straße 10, W-3300 Braunschweig, F.R.G. consistent theoretical treatment is at present not available [15,16], although a lot of work has been done for the static case (co = 0) [17][18][19][20][21][22], So it seems worth to estimate the temperature-and wavelength-dependence of the second refractivity virial coefficient on the basis of the first treatment given by Buckingham [1] for atoms and small molecules.…”

Correction to the Clausius–Mosotti equation: The dielectric constant of nonpolar fluids from Monte Carlo simulations

“…At high densities, the molecules can modify each others' structure and the apparent polarizability of colliding molecules can be different from that of the isolated molecules. The difference, the incremental polarizability can be studied by collision-induced light scattering 43,44 . The effect of anisotropic, tensorial polarizability can also be important at high densities 45 .…”

Accurate pair‐anisotropy models out of a set of input experimental moments via a novel non‐linear inversion method

“…For sufficiently dilute gaseous media, pairwise interactions are practically the only ones to participate. 2 However, to envision a good description of the induced anisotropy of an atomic or molecular pair, a multitude of diffused orbitals must be satisfactorily calculated. Consequently, the quantitative determination of pair-anisotropies requires expensive large-scale quantum-chemistry computations and sophisticated ab initio methods.…”
