Optical constants, dielectric constants, molar absorption coefficients, molar polarizability, vibrational assignment and transition moments of liquid iodobenzene between 4000 and 400 cm(-1) at 25 degrees C

Infrared optical constants, molar absorption coefficients, dielectric constants, molar polarisabilities, transition moments and dipole moment derivatives of liquid N,N-dimethylacetamide-carbon tetrachloride mixtures

Mid-infrared spectra of the DMA-carbon tetrachloride system by transmission and single- and multiple-reflection ATR technique in the whole composition range (0<x(DMA)≤1), recorded at room temperature between 5000 and 850cm(-1) are presented. The complex optical constant, molar absorption coefficient, complex dielectric constant and complex molar polarisability spectra are determined. The wavenumber × imaginary molar polarisability spectra were fitted to classical damped oscillator model, which gives intensities, vibrational transition moments, and dipole moment derivatives with respect to normal coordinates of the corresponding vibrations.
