F The Furanone Compound Is Immobilized By Using An Interlayer Of Polyacrylic Acid Paa Or Polyethylene Glycol Peg 1 (184.8 KiB) Viewed 14 times

(f) The furanone compound is immobilized by using an interlayer of polyacrylic acid (PAA) or polyethylene glycol (PEG) (see Figure 5). The thickness of a PEG interlayer is 2.84 nm and that of a PAA one is 2 nm. What is the inelastic mean free path (IMFP) for electrons travelling through a PEG interlayer if the electron signal is attenuated by 53%? At what angle would photoelectrons travelling through a PAA interlayer need to be measured, for them to be attenuated by the same amount? No marks will be given if no working is shown.
