Schiebener et al. published a formulation for the refractive index of water and steam in 1990 [J. Phys. Chem. Ref. Data 19, 677 (1990)]. It covered the ranges 0.2 to 2.5 μm in wavelength, −12 to 500 °C in temperature, and 0 to 1045 kg m−3 in density. The formulation was adopted by the International Association for the Properties of Water and Steam (IAPWS) in 1991. In the present article, the data, after conversion to ITS-90, have been refitted to the same functional form, but based on an… 

Water density and polarizability deduced from the refractive index determined by interferometric measurements up to 250 MPa.

It is shown that the Sellmeier coefficients can be straightforwardly linked to the pressure, allowing the determination of the refractive index of water for any wavelength or pressure, and the polarizability of water as function of pressure and wavelength is calculated by means of the Lorentz-Lorenz equation.

Mixture model description of the T-, P dependence of the refractive index of water

In this paper the temperature/pressure dependence of the refractive index of liquid water is analyzed using the two-state outer-neighbor mixed bonding structural model. So far, this theoretical model

Measurement of the refractive index of distilled water from the near-infrared region to the ultraviolet region.

By the minimum deviation method using a prism shaped cell, the absolute refractive indices of high-performance liquid chromatography distilled water were measured at the wavelengths from 1129 to 182 nm, at the temperature of 19 degrees C, 21.5 degrees C; and the coefficients of the four-term Sellmeier dispersion formula were determined by using theRefractive indices at each temperature.

Comment on “Mixture model description of the T-, P dependence of the refractive index of water” [J. Chem. Phys. 114, 3157 (2001)]

In a recent paper modeling the refractive index of water, some data taken at the National Bureau of Standards in the 1930s were not handled correctly. The problems, which do not invalidate the model,

Equation of state, refractive index and polarizability of compressed water to 7 GPa and 673 K.

The equation of state (EoS), refractive index n, and polarizability α of water have been determined from acoustic velocity measurements conducted in a resistively heated diamond anvil cell using Brillouin scattering spectroscopy, suggesting strong intermolecular interactions in H(2)O that are consistent with the prevalence of the hydrogen bond network in the fluid.

Refractive Index of Supercooled Water Down to 230.3 K in the Wavelength Range between 534 and 675 nm.

Knowledge of the refractive index of water in the deeply supercooled metastable liquid state is important, for example, for an accurate description of optical reflection and refraction processes

Effect of Dissolved Air on the Density and Refractive Index of Water

The effect of dissolved air on the density and the refractive index of liquid water is studied from 0 to 50° C. The density effect is calculated from the best available values of Henry’s constants

Concentration dependent refractive index of a binary mixture at high pressure.

While the measured refractive indices agree very well with predictions given by Looyenga, the measured concentration CFs show deviations from the latter of the order of 6% and more than the double from the Lorentz-Lorenz predictions.

Reference Correlations for Thermophysical Properties of Liquid Water at 0.1 MPa

Simple but highly accurate correlations have been developed for the thermodynamic properties (including density, heat capacity, and speed of sound), viscosity, thermal conductivity, and static

The Refractive Index of Amorphous and Crystalline Water Ice in the UV–vis

Amorphous solid water (ASW) is found on icy dust grains in the interstellar medium (ISM), as well as on comets and other icy objects in the outer solar system. The optical properties of ASW are thus
