研究了静电溶剂效应和氢键作用对1-甲基-2-吡啶酮红外、紫外吸收和荧光光谱的影响。结果表明，随着溶剂极性的增加，1-甲基-2-吡啶酮的紫外吸收峰和荧光峰均向短波方向移动，且在与醇类和氯仿形成氢键时，这些吸收峰发生蓝移。通过光谱研究，确定了1-甲基-2-吡啶酮的激发态偶极矩、1-甲基-2-吡啶酮与乙醇形成氢键的基态和激发态平衡常数以及基态焓变。
The electrostatic solvent effects and hydrogen-bonding interactions on IR and UV absorption and fluorescence spectra of 1-methyl-2-pyridone has been investigated. It was found that the UV absorption and fluorescence bands of 1-methyl-2-pyridone shifted towards the shorter-wavelength region with increasing solvent polarity and that these bands exhibited a blue shift on hydrogen bond formation with alcohols and chloroform. The excited-state dipole moment of 1-methyl-2-pyridone, and the equilibrium constants in the ground and excited states and enthalpy change in the ground state for hydrogen-bond formation between 1-methyl-2-pyridone and ethanol have been determined from the spectroscopic studies.
