Their high refractive index is also indicative, but other materials have similar refractivity.

When examined under the microscope, the capsule appears 'swollen' due to an increase in its refractivity.

Even with two flashlights and the unusually high refractivity of the mysterious material, shadows ruled the room.

The refractive index is related to the molar refractivity, structure and weight of the monomer.

The use of lead glaze has several advantages over alkali glazes in addition to their greater optical refractivity.

The positronic brain was a platinum-iridium sponge, with a high refractivity; it wouldn't melt easily.

These include light scattering, viscosity, refractivity, conductivity, ultra-violet absorption, etc.

In general, high molar refractivity and low molar volumes increase the refractive index of the polymer.

It arises yet again in the context of refractivity, in which it is known as the Lorentz-Lorenz equation.

Boron differs from the other group members in its hardness, refractivity and reluctance to participate in metallic bonding.

The movement of air in the beam path will cause refractivity fluctuations, which (if the laser frequency is stable) means that the wavelength is fluctuating.

The amount of bending can be related to the refractive index by using an Abel transform on the formula relating bending angle to refractivity.

A colorless form of zirconia similar in appearance and refractivity to diamond, and used as a substitute for diamonds in inexpensive jewelry.

Phosphorus-containing groups, such as phosphonates and phosphazenes, often exhibit high molar refractivity and optical transmittance in the visible light region.

The molar refractivity A of a gas is related to its refractive index n by the Lorentz-Lorenz equation:

And Dr. Harlow explained that a crystalline structure's primary power has to do with refractivity of light, not electricity - which is what makes them visual marvels.

In recent optical crystallography, Gladstone-Dale constants for the refractivity of ions were related to the inter-ionic distances and angles of the crystal structure.

As fuel is pumped to the engine, it passes an optical sensor that measures the percentage of methanol by the refractivity, or light-bending properties, of the fuel.

Its goals were to measure interplanetary and Venusian magnetic fields, charged particles, plasmas, radio refractivity and UV emissions of the Venusian atmosphere.

In this vein, the professor's main interest lay in determining the relation of the chemical and physical properties of sea water - notably the specific gravity, refractivity, and electrical conductivity.

The magnitude of the refraction depends on the gradient of refractivity normal to the path, which in turn depends on the gradients of density and the water vapour content.

He has recently switched his focus to developing a new set of climate instruments called CLARREO (Climate Absolute Radiance and Refractivity Observatory).

Molar refractivity, , is a measure of the total polarizability of a mole of a substance and is dependent on the temperature, the index of refraction, and the pressure.

The refractivity of a single molecule is the refractive volume k(MW)/An in nm, where MW is the molecular weight and An is Avogadro's number.

The ionic refractivity depends on 1/d, where d is the inter-ionic distance, indicating that a particle-like photon refracts locally due to the electrostatic Coulomb force between ions (Teertstra 2008a).
