Figure 2
Calibration of the SRCD spectrometer. (a) Absolute calibration of the monochromator using N2 peaks in the VUV. The chamber was purged with nitrogen, spectral acquisition settings were 0.1 nm steps, 300 ms time constant, HT current constant. Peak positions measured in volts of DC current correspond to the literature-referenced absorption peaks. For routine optimization of the optical alignment and electronic recording, peak positions and amplitudes ratio are verified, with a standard CSA solution 6.3 g L−1 in 100 µm pathlength at 298 K (b). The thick line shows the CD signal measured in mdeg; the thin line corresponds to the recorded HT measured in volts. |
