Webb6 apr. 2024 · Specifically, it is revealed that the formation of peroxidation products could be significantly prevented by the selective cleavage of C–O bonds in CH 3 O* intermediates instead of metal–O bonds, which is proved by the combination of density functional theory calculations and in situ infrared spectroscopy based on isotope labeling. Webbcauses motion of electrons in bonds. These moving electrons reemit light of the same wavelength for elastic scattering. Light scattering is sensitive to the mobility of electrons in bonds. The mobility of electrons in a bond is called the Polarizability of the bond, i.e. a measure of how easy it is to move electrons and polarize a bond.
