The 1 H, 13 C and 77 Se chemical shifts and the 1 J [C(Me)H(Me)], 1.2 J (SeC) and 2 J (SeH) coupling constants in 14 para ‐ or meta ‐substituted selenoanisoles, RC 6 H 4 SeCH 3 , have been measured and the dependence of these parameters on the electronic effects of the substituent R is discussed. A significant (up to 6 ppm) deviation from additivity of the substituent influence on the shielding of the 13 C ring carbons has been found.
