Direct observation of structural heterogeneity and tautomerization of single hypericin molecules

Quan Liu, Frank Wackenhut, Liangxuan Wang +6

Tautomerization is a fast chemical reaction where structures of the reactants differ only in the position of a proton and a double bond. Tautomerization often occurs in natural sub…
