“…Effective Kirkwood correlation factor 'g eff ' for ACN and CBZ at 301º K is found to be 0.76, 0.60 respectively. It is seen that for all concentrations of binary mixtures, g eff value is < 1, close to unity at 301º K which indicates the insufficient interaction with anti-parallel orientation of electric dipoles (Joshi and Kumbharkhane, 2012;Sengwa et al, 2009;Kadam et al, 2013). The g eff values increases with increase in ACN in CBZ, confirms strong interaction in ACN rich region and weak interactions in CBZ region which is indication of deviation from unity (Shere, 2020;Ingole et al, 2018).…”

Molecular interactions between CBZ-ACN at 8.845 GHz of microwave frequency region confer structural behavior of molecules such that either monomers or multimers are present in the agreed binary mixtures. Effect of microwave frequency on molecular interactions and hydrogen bonding between C≡N (nitrile) molecule and Cl (chlorine) molecule of CBZ and ACN binary solutions has been studied using X-band microwave technique at 301ºK. Co-operative dynamics and hydrogen bonding between nitrile and chlorine group molecules has been thoroughly explicated thereby obtaining static dielectric constant, excess permittivity, Kirkwood correlation factor using Luzar model and Bruggeman factor.

“…However, 1,4-dioxane (DX) [C4H8O2] is a non-hydrogen bonded liquid treated as a non-polar solvent, having a very small dipole moment and no pair formation takes place between two DX Molecules [12]. Many studies have been conducted to obtain dielectric properties, hydrogen bonding, thermodynamic behavior, dielectric relaxation, and structural behavior using DX as a solvent [13][14][15][16][17].The main objective of this paper is to study the dielectric behavior of a polar and non-polar molecule i.e. binary mixture of ACRN in 1, 4-DX by using TDR at various temperatures in the frequency range from 10 MHz to 30 GHz.…”

The frequency-dependent complex permittivity spectra (CPS) of acrylonitrile (ACRN) and 1,4-dioxane (DX) binary mixture in the range from 10 MHz to 30 GHz were measured using the time domain reflectometry (TDR) technique. Experimentally obtained CPS was fitted into the Debye equation. Dielectric relaxation behaviors that depend on temperature and concentration were discussed. The obtained dielectric parameters are reported. The Kirkwood correlation and Bruggeman factor have been used to analyze the molecular association and hydrogen bonding interactions in the mixture.

“…12 Much research work has been carried out on dielectrics of liquids such as alcohols, bio-polymers, etc. [13][14][15][16][17][18][19][20] The key point of these studies were to understand the structure of benzylamine in its pure and alteration of benzylamine in 1,2,6-hexanetriol. The present work deals with time domain dielectric relaxation study of benzylamine in 1,2,6-hexanetriol at 25 C in the frequency range of 10 MHz to 30 GHz.…”

The dielectric properties of binary mixtures of benzylamine-1,2,6-hexantriol mixtures at different volume fractions of 1,2,6-hexanetriol have been measured using Time Domain Reflectometry (TDR) technique in the frequency range of 10 MHz to 30 GHz. Complex permittivity spectra were fitted using Havriliak-Negami equation. By using least square fit method the dielectric parameters such as static dielectric constant (" 0 ), dielectric constant at high frequency (" 1 ), relaxation time (ps) and relaxation distribution parameter () were extracted from complex permittivity spectra at 25 C. The intramolecular interaction of different molecules has been discussed using the Kirkwood correlation factor, Bruggeman factor. The Kirkwood correlation factor (g f ) and effective Kirkwood correlation factor (g eff ) indicate the dipole ordering of the binary mixtures.
