摘要: The solvent relaxation and orientational dynamics of coumarin 153 (C-153) was investigated in N,N-dimethylethanolammonium formate (DAF) with a variation temperature. DAF is protic room-temperature ionic liquid, comprised nonaromatic cations. Both C-153 are linearly well-correlated the bulk viscosity at different temperatures. We optimized geometry using quantum chemical calculations density functional theory methods. structure shows nonbonded interaction between cation anion, which suggests that hydrogen bond formed atoms attached to nitrogen atom oxygen anion DAF.
