Figure 3
Difference spectra (X-ray shutter open − X-ray shutter closed) showing the appearance of a broad feature centred at 600 nm in solutions of 50% (v/v) MPD (recorded in this study) and 40% (v/v) glycerol [recorded at the ESRF (McGeehan et al., 2009)] at 100 K during X-ray exposure. The discontinuity in the glycerol spectrum at 680 nm is a deuterium lamp artefact. |
