A study was made on the spectroscopic properties of 4-hexylresorcinol (4HR) in several solvents at room temperature. Absorption and emission spectra were slightly affected by solvent polarity. Stokes' shifts were small (approximately 3000 cm(-1)) and the fluorescence quantum yields varied between 0.05 and 0.68, depending on the solvent. The spectral shifts were correlated with different solvent scales. Multiple regression analysis indicates that both non-specific solute-solvent interactions as well as specific solute-solvent interactions (such as hydrogen bonding) play an important role in the position of the Stokes' shift and on the fluorescence quantum yield in the solvents under study.
在室温下，对4-己基间苯二酚（4HR）在几种溶剂中的光谱性质进行了研究。吸收光谱和发射光谱受溶剂极性的影响较小。斯托克斯位移较小（约3000 cm⁻¹），荧光量子产率在0.05至0.68之间变化，具体取决于溶剂。光谱位移与不同的溶剂标度相关。多元回归分析表明，非特异性溶质-溶剂相互作用以及特异性溶质-溶剂相互作用（如氢键）在所研究的溶剂中，对斯托克斯位移的位置和荧光量子产率都起着重要作用。
