We show that femtosecond stimulated Raman spectroscopy can record excited-state spectra in the absence of actinic excitation, if the Raman pump is in resonance with an electronic transition. The approach is illustrated by recording S1 and S0 spectra of trans-azobenzene in n-hexane. The S1 spectra were also measured conventionally, upon nπ* (S0 → S1) actinic excitation. The results are discussed and compared to earlier reports.
我们表明，如果拉曼泵浦与电子跃迁共振，飞秒受激拉曼光谱能够在不存在光化激发的情况下记录激发态光谱。通过记录正己烷中反式偶氮苯的S1和S0光谱来说明该方法。S1光谱也按照常规方法在nπ*（S0→S1）光化激发下进行了测量。对结果进行了讨论并与早期报告进行了比较。
