Abstract

The analysis of the NMR spectra of seleninium and 1‐and 2‐benzoseleninium cations, recorded in deuterotrifluoroacetic acid, is reported. The effects of condensation on the spectral parameters of the protons of the seleninium ring were examined with particular reference to the shift to higher values of δ: this was consistent with the q values calculated by the HMO method. The ^3^J(HH) and ^4^J(HH) variations, including an interesting variation regarding the through‐selenium ^4^J coupling, are also discussed.
