On the performance of molecular polarization methods. I. Water and carbon tetrachloride close to a point charge
No full textThe three main methods to implement molecular polarization (point dipoles, fluctuating charges, and shell model) are tested against high levelab initiocalculations for a molecule (water, carbon tetrachloride) close to a point charge (at the distance of a lithium or magnesium ion). The goal is to check whether an approximation (linear polarization) strictly valid at large intermolecular distances is sufficiently accurate for liquid state molecular dynamics simulations, where strong polarization effects are to be expected at short separations. The monitored observable is the molecular dipole moment as a function of the charge-molecule distance for selected molecular orientations. Analytic formulas are derived for the components of the molecular polarization tensor, facilitating the optimization of the performance for each polarization method as a function of its underlying parameters. Overall, the methods studied provide a remarkably good representation of the induced dipole, with no divergences appearing even at the shortest distances. For water close to a monovalent point charge the point dipole model, implemented with one or three dipoles, accurately reproduces the water dipole moment at all distances. Deficiencies appear as the molecular polarizability and/or charge increase: basically, theab initioinduced moments grow faster at intermediate distances than the linear increase characteristic of the phenomenological polarization methods, suggesting that nonlinear effects (hyperpolarizability) cannot be neglected in these cases. Regarding the capabilities of each method, the point dipole method is the one that performs best overall, with the shell model achieving acceptable results in most instances. The fluctuating charge method shows some noticeable limitations for implementations of comparable complexity (in terms of the number of sites required)
Happytime Series #24
No full textThis booklet presents two irregularities or anomalies. First, it is missing four pages at its center. WL seems just to have ended, and we find ourselves suddenly on the last page of The Wolf Who Became a Shepherd. The second anomaly grows out of the fact that this edition acknowledges that it is a translation by arrangement with Librairie Hachette. The book in question seems to be La Fontaine: Fables from Hachette in 1953. Three of that book's four stories are presented here, including the exact same pictures. The anomaly is that that book proclaims Imagées par Romain Simon, while this has Pictures by Pierre Probst. The texts for what we have here follow La Fontaine's versions. As I say concerning that book, of the simple, lively colored illustrations, two stand out for me. Both illustrate MSA. The former, on the title-page, shows a disgruntled father with a happy child as both sit on the beast. The latter, on the last page, pictures the two flanking the beast and walking arm-in-arm with it. Now all three are happy!Traduit du Latin par E. Panckouck
On the performance of molecular polarization methods close to a point charge
No full textThe induced dipole moment of a water molecule close to a point charge (with the radius of Na+ or Be2+) is computed with the three main methods to implement molecular polarization (point dipoles, fluctuating charges and shell model). The results are compared with high level ab initio calculations and studied as a function of the charge-molecule distance for selected molecular orientations. For the single charge case rather good estimations of the ab initio induced dipole are obtained, with no significant divergences appearing at the shortest distances. Nevertheless, these (linear polarization) methods fail as the charge increases, suggesting that nonlinear effects may not be neglected. Regarding the capabilities of each method, the point dipole method is the one that performs better overall, with the shell model achieving acceptable results in most instances. The fluctuating charge method has some noticeable limitations for implementations with a similar number of interaction sites
Polarization damping in halide-water dimers
No full textHigh level ab initio calculations show that the self-induced dipole moment of a halide-water dimer deviates from the usually employed point dipole model, with a substantial nonlinear damping at separations corresponding to the first hydration shell. The total dipole moment is rather similar along the halide series, with the maximum value decreasing as anionic polarizability increases. A new implementation of the Thole damping method satisfactorily reproduces the dipole moment at all separations for the most probable configurations
