Far-infrared optical constants of liquid acetonitrile at 238 to 343 K as measured with a synchrotron radiation source
T. Ohba,Shun-ichi Ikawa +1 more
TL;DR: In this article, a theoretical expression for transmittance of a cell filled with liquid was obtained as a function of the optical constants of the liquid, assuming an analytical form with seven parameters for the absorption coefficients, the refractive indices were analytically calculated by the Kramer-Kronig relation.

Spin-chemical approach to photochemistry: reaction control by spin quantum operation
TL;DR: In this article, the contribution of spin chemistry (in particular, magnetic resonance-related chemistry) to the photochemical field is briefly introduced, and the most important physical conclusions are the introduction of the spin phase relaxation termed singlet-triplet (S − T ) and triplet-triplets (T - T ) dephasing, instead of the traditional concepts of longitudinal (T 1 ) and transversal relaxations (T 2 ).

Absorption and dispersion studies in the range 10–1000 cm−1 using a modular Michelson interferometer
TL;DR: In this article, a modular Michelson interferometer has been developed for use as a Fourier transform spectrometer providing both absorption and refraction spectra, and it has been shown that a few simple modifications enable the upper frequency limit to be raised to 1000 cm−1.

Studies of molecular motions and interactions in acetonitrile
TL;DR: In this article, microwave and far-infrared absorption coefficients are reported for acetonitrile over the whole concentration range in carbon tetrachloride solution. And they are used to compute dipole reorientational correlation functions and relaxation times as a function of concentration.
