## Abstract Significant variations of thiapyrylium chemical shifts, by comparison with their thienohomologues, are shown by ^1^H n.m.r. spectra of furo[3,2โ€c]thiapyrylium and furo[2,3โ€c]thiapyrylium perchlorates. The observed changes can be ascribed to a different distribution of the electron charg
