The dipole moments of 1:1complexes formed between phenol and aniline, ochloroaniline, and p-chloroaniline were measured in carbon tetrachloride at a temperature of 303 K. The dipole increments for these systems were calculated based on molecular orbital theory using bond angle data. The observed increase in dipole moment values provides evidence of hydrogen bonding between phenol and all three anilines. As the concentration of phenol increases, the FT-IR intensity decreases, and there is a slight increase in the half-width of the amine band. These observations suggest the formation of 1:1 complexes between phenol and anilines.

“…62 A potential drawback of choosing PC as a mixing partner may be its large dipole moment of about 5 D, 63–65 while for PhOH some solution studies indicate an “infinite dilution” value of “only” 1.5 D. The sizeable dependence of PhOH's dipole moment on concentration and solvent could be taken as a hint for self-association effects. 66,67…”

“…62 A potential drawback of choosing PC as a mixing partner may be its large dipole moment of about 5 D, [63][64][65] while for PhOH some solution studies indicate an ''infinite dilution'' value of ''only'' 1.5 D. The sizeable dependence of PhOH's dipole moment on concentration and solvent could be taken as a hint for self-association effects. 66,67 The dipolar response of PhOH mixtures with PC are thus expected to comprise significant contributions also from the van der Waals liquid. To enable an additional perspective on the relaxation properties of PhOH in PC that is not sensitive on the molecular dipole moments, apart from dielectric spectroscopy, we performed shear mechanical measurements.…”

The nature of hydroxylamine complexes was identified through the formation of hydrogen bonding between alcohols (methanol, ethanol, propanol, and butanol) with aniline from the dielectric measurements like dielectric constant, density and refractive index. From these measurements, the dipole moment of hydroxylamine complex was determined from the Huysken's method origin of Onsager model also evaluated the dipolar increment. The enthalpy changes due to bond formation obtained from the dipolar increment. The dipole moment of the both cis and trans structure are determined and tabulated, the dipole moment values of the trans are higher than the cis structure it may complex is form the trans structure. The value of dipole moment of the complex, dipolar increment and enthalpy changes concluded complex formation mainly due to the polarization only. These values indicate the order of the complex methanol > ethanol > propanol > butanol, aniline as one of the component.
