“…A combination of spectroscopic techniques has also proven useful when studying the heteromolecular H-bonding interactions between a mixture of nitrogen-based acceptors (amides/amines) and oxygen-based donors (alcohols, carboxylic acids, and water) . The presence, together with conformational analysis, of the H-bonds in mixtures of dimethylacetamide–butanol, aniline–isobutanol, cyanoacetamide–water, and N -methylpyrrolidone–glycerol was confirmed using a combination of dielectric spectroscopy and FTIR. – …”

A study focused on the correlation among dielectric properties, molecular structure, and H-bonding is presented using liquid formamides with increasing carbon chain lengths as a model series. 1 H NMR is used to determine the extent of H-bonding via Abraham solute hydrogen bond acidity parameter, A. The results show a clear quantitative correlation, with higher A linked with increased relaxation times (τ) and a drop in the static dielectric constants (ε s ), with differences between the 1 and 2°amides observed. Overall, the findings advance our understanding of the intricate relationship between dielectric properties and H-bonding, with potential applications toward the design of materials exhibiting tailored dielectric properties and the study of amide-containing molecules (such as DNA, peptides, proteins, and nylon polymers) and other liquids which may associate via H-bonding.

“…11,12 Recently, many works on dielectric and other properties of liquids have been reported. [13][14][15][16][17][18][19] The study of dielectric properties of EGME in particularly the determination of the static and the high-frequency dielectric constant can provide a good deal of information about their molecular structure and the intermolecular interaction. The broadband TDR is a powerful technique to measure the complex dielectric permittivity of EGME as well as binary mixtures over a wider frequency range.…”

The Complex permittivity spectra of glycol ether (GE) compounds such as ethylene glycol mono-methyl ether (EGME) with water mixture over entire concentration range and in temperature range of 10–25∘C have been determined using Time Domain Reflectometry (TDR) technique in the frequency range 10[Formula: see text]MHz to 50[Formula: see text]GHz. The complex permittivity spectra for EGME-water were fitted in the Cole–Davidson model. The Static dielectric constant ([Formula: see text], Relaxation time ([Formula: see text], effective Kirkwood correlation factor ([Formula: see text], excess permittivity ([Formula: see text], thermodynamic parameters (activation enthalpy and activation entropy) and Bruggeman factor ([Formula: see text] have been calculated by the nonlinear least square fit method. The intermolecular interactions between EGME-water binary mixtures suggest the nonlinear behavior of dielectric parameters. The contribution of hydrogen bonding interactions among the solute–solvent mixtures is confirmed by Excess properties and Bruggeman factor.
