Summary: | The εEvsϕ2 (b and d) suffers quantitatively a large change from the εEvsX2 plot (a and c) but, they qualitatively agree each other.
[Display omitted]
•τ values: AcAc exists as monomers in keto and enol forms.•τ values: 1:1 complexation of AN/DMSO with AcAc.•gf values: non-classical H – bonds between AN/DMSO and AcAc.•O-H hydrogen of enol AcAc: not participating in homo/heterointeraction.•εEvsϕ2 and εEvsX2: quantitatively differs but, qualitatively agree each other.
H – bond interactions between acetonitrile(AN)/dimethyl sulfoxide(DMSO) and acetylacetone (AcAc) have been investigated using time domain reflectometry studies. The relaxation time values confirm that 1:1 complex has been formed between AN/DMSO and AcAc, and both the keto and enol forms of AcAc exist as monomers. Antiparallel and parallel alignment of AN/DMSO – AcAc H – bonded dipoles in AN/DMSO and AcAc rich solutions, respectively, have been identified. The gf values indicate that non-classical H – bond interactions are operative in AN/DMSO – AcAc solutions. The εEvsϕ2 suffers quantitatively a large change from the εEvsX2 plot but, they qualitatively agree each other. |
