Electron tunneling spectroscopy has been used to characterize the degradation of beta-D-fructose after electron bombardment in a scanning electron microscope. The decrease in intensity of various vibrational bands is correlated with structural changes in the molecule, thereby providing a detailed picture of the degradation process.
