The charge is the electron density difference between atomic state and molecular state of S atom. The results show that only the S atom in ETL is negatively charged. It means that the ethyl group donates its electrons to S atom in ETL. Moreover, other sulfur compounds show that S atom donates its electrons to other groups, especially the phenyl group, which leads to a positively charge on S atom.
