吸收光谱和振子强度已被确定为液体，苯，甲苯，六氟苯，四甲基硅烷，2，2-二甲基丁烷，和2，2，4-三甲基戊烷的光谱范围从120至300 nm，并与气相光谱进行比较。凝聚的效果表现得最明显的过渡分配到较高的状态相对较大的空间范围或过渡与高频谱密度的振子强度。然而，补偿效应似乎减轻了六氟苯和四甲基硅烷的缩合效应。
Absorption spectra and oscillator strengths have been determined for the liquids, benzene, toluene, hexafluorobenzene, tetramethylsilane, 2,2-dimethylbutane, and 2,2,4-trimethylpentane over a spectral range from 120 to 300 nm and compared with gas phase spectra. The effect of condensation manifests itself most obviously for transitions assigned to upper states of relatively large spatial extent or for transitions with a high spectral density of oscillator strength. Compensating effects, however, appear to mitigate the effect of condensation for both hexafluorbenzene and tetramethylsilane.
