(a) Thermal melt series for MEG-14 in aqueous solution from 5°C (bold) to 85°C (dotted), in 10°C steps (intermediate temperatures in gray, the arrows indicate the direction of the spectral changes). The spectrum taken at 25°C after heating is the dashed line. (b) Plots of the magnitudes of the peaks at 184 nm (square), 198 nm (triangle), and 222 nm (circle) during the heating process.
