Eli, is polarizability really all that relevant here ? ❋ EliRabett (2010)
The polarizability of atoms scales inversely with the charge density, thus hydrogen could get pretty close to a neutral molecule before the dispersion forces took over. ❋ EliRabett (2010)
To be sure, decreasing the polarizability will tend to pull sigma, the point where the red curve crosses the x axis, outward, so there is some effect, but I don't think it's enough to explain RayP's observation. ❋ EliRabett (2010)

Both provided accurate results about the polarizability of water molecules. ❋ Unknown (2010)
The team began by obtaining highly accurate data on the polarizability of a collection of up to 12 water molecules. ❋ Unknown (2010)
The biological membrane in this model is represented by a simplified description using three structureless homogeneous slabs of dielectric continuum with a low relative dielectric constant assigned to the hydrocarbon region due to its low molecular polarizability The 5 slab membrane model used in the current study with the relative dielectric constant along the direction normal to the model membrane plane. doi: 10.1371 / journal. pone.0004799.g006 ❋ Unknown (2009)
The empirically known polarizability was likewise unexplainable. ❋ Unknown (2008)
(SERS) experiments can teach us about wavelength dependence of the molecular polarizability tensor. ❋ T. Shegai (2008)

These internal forces resist the polarization and determine the magnitude of the polarizability. molecular physics. ❋ Unknown (2008)
Sometimes one defines the polarizability in SI units by the equation ❋ Unknown (2008)
For a molecular dielectricum consisting of a single kind of non-polar molecules, the proportionality factor it is assumed that the molecular polarizabilities are additive; if this is not the case, the expression can still be used when α is replaced by an effective polarizability. ❋ Unknown (2008)
Comparing the second-order energy U (2) with the induction energy Uind gives a quantum mechanical expression for the polarizability tensor: electromagnetic wave with electric component Ecosωt the polarizibility becomes a function of the angular frequency speed of light. ❋ Unknown (2008)
σ can be approximated by a scalar and is known as the shielding constant. depends upon the electron density as well as polarizability which vary substantially depending upon the nature of the molecule and the location within the molecule. ❋ Unknown (2009)
