摘要: The vibrational frequencies of the CO + CC band diphenylcyclopropenone and NH2 stretching p-aminobenzonitrile were determined in various room temperature ionic liquids (RTILs). frequency shifts mode compared with Kamlet α values, β values. A nearly linear relationship was obtained for both parameters, although solvatochromic parameters more sensitive to changes cation species. Vibrational calculations a 1 : 1 cluster RTIL anions using DFT theory reproduced observed fairly well. CN well by combination dipolarity hydrogen-bond donating accepting Raman shift solute molecule.
