Temperature dependence of the optical constants for liquid H2O and D2O in the far IR region
TL;DR: In this paper, the optical constants n and k of liquid H 2 O and D 2 O were calculated by iteration using the Kramers-Kronig transformation which has been adapted to the problem of fringe correction for a flat absorbing sample in contact with highly refractive silicon substrates.

Isotope effects in liquid water by infrared spectroscopy. III. H2O and D2O spectra from 6000 to 0 cm(-1).
Jean-Joseph Max,Camille Chapados +1 more
TL;DR: The infrared spectra (IR) of pure liquid light and heavy water were obtained with attenuated total reflection (ATR) and transmission measurements in the mid-IR and far-IR with new optical properties (n and k) that can now be used as standards for liquid H(2)O and D( 2)O.

Internal Reflection Spectroscopy
TL;DR: The history of internal reflection spectroscopy (IRSIRS) as mentioned in this paper began nearly two centuries ago with the observation by Newton [l] of an evanescent field in a lower index of refraction medium in contact with a higher one in which a propagating wave of radiation undergoes total internal reflection (TIR).

The Bouguer-Beer-Lambert Law: Shining Light on the Obscure.
TL;DR: This review will be an essential tool towards a full understanding of optical spectra and their quantitative interpretation based not only on oscillator positions, but also on their strengths and damping constants.

Theory of Midinfrared Absorption Microspectroscopy: I. Homogeneous Samples
TL;DR: The model provides a framework to quantify spectral distortions that may limit the accuracy of information or present confounding effects in microspectroscopy and provides guidance for developing experimental methods and future instrument design by quantifying distortions in the recorded data.

Relation between Surface Roughness and Specular Reflectance at Normal Incidence
H. E. Bennett,J. O. Porteus +1 more
TL;DR: In this paper, the roughness of a plane surface is related to its specular reflectance at normal incidence, and expressions for the case when the root mean square surface roughness is small compared to the wavelength of light are presented.

A Redetermination of Some Optical Properties of Calcium Fluoride
TL;DR: In this paper, a synthetic and a natural prism of calcium fluoride were fitted to a three-term Sellmeier dispersion formula of the form: n2 − 1 = ∑Ajλ2/(λ2 − λj2).

Reflection of Light by a System of Nonabsorbing Isotropic Film–Nonabsorbing Isotropic Substrate with Randomly Rough Boundaries
TL;DR: In this article, a scalar theory of light scattering on a system consisting of a nonabsorbing isotropic film and a non-absorbing substrate with both boundaries (air-film and film-substrate) rough is considered.
