The solvent Stark effect on the spectral shifts of anthracene is studied with temperature‐dependent solvatochromic measurements. The Stark contribution Δv_Stark to the absorption shift Δv_p in polar solvents is measured to be Δv_Stark=(53±35) cm⁻¹, in reasonable agreement with dielectric continuum theory estimate of 28 cm⁻¹, whereas the major shift Δv_p∼300 cm⁻¹ presumably originates from the solute quadrupole. We pay attention to the accurate correction of Δv_p for the nonpolar contribution that is crucial when the shifts are modest in magnitude.

从温度依赖性蒽的溶剂变色位移评估溶剂的斯塔克效应。

用温度依赖性溶剂变色法研究了溶剂蒽对蒽光谱移动的斯塔克效应。斯塔克贡献Δ v_斯塔克于吸收移位Δ v _p在极性溶剂中被测量为Δ v_斯塔克=（53±35）厘米^-1，与28厘米介电连续体理论估计合理的协议^-1，而主要移位Δ v _p〜300厘米^-1从溶质四极可能起源。我们注重Δ的准确校正v _p的非极性的贡献时，位移是大小适中是至关重要的。
