WebDec 31, 2015 · Yes, but not through direct excitation into a dissociated state. This is explained in Ref. 1: Unfortunately, measuring D0 by direct photoexcitation of H2O from its vibrational ground state to the dissociation threshold is prohibited by the negligibly small intensity of such an overtone transition. WebThe primary structure of the polymer will survive sonication because of the strong covalent bonds. But, if the polymer is already cross-linked, sonication cannot break down the cross-linking. WebHydrolysis is a chemical reaction during which polymers (large molecules) break down into monomers (small molecules).. During hydrolysis, covalent bonds between monomers break, which allows for the breaking down of polymers. Bonds are broken down using water.Hydro literally means 'water', and - lysis stands for 'to unbind'. meaning of a raven
