Cavity-Enhanced Spectroscopy in Condensed Phases: Recent Literature and Remaining Challenges

Figure 3

(a) Plot of cavity enhancement factor versus wavelength. (b) Plot of indicated absorbance versus wavelength for Sudan black dye in a variety of solvents. The blue trace is a single-pass absorption spectrum, while the remaining traces are CES experiments. Notice that the CES spectra are distorted at certain wavelengths due to variation in the cavity enhancement factor. Figures reproduced with permission from Seetohul et al. [21].
