## Abstract High resolution ^1^H, proton coupled ^13^C and broad‐band decoupled ^13^Cο£Ώ{^1^H} spectra have been recorded for pyrylium, thiapyrylium and seleninium tetrafluoroborates in CD~3~CN. Analysis of these spectra has provided accurate values and relative signs of all ^1^H,^1^H and ^13^C,^1^H
