Figure 3
Polyethylene glycol (PEG) solutions of varying molecular weight exhibit a transient solvated electron peak in the 450–700 nm range. Peak intensity is influenced by film thickness. With increasing dose the peak diminishes, and a second absorption feature emerges below 400 nm, most prominently in the 100% PEG 400 sample. The concentration of samples is given as percentage (v/v). Colour coding for 2D spectra is from red (start) to blue (end). In the 3D spectra, colour coding represents absorbance change with dose from blue (minimal change) to red (maximal change).
