It is shown that the nuclear effects playing a relevant role in deep inelastic scattering of polarized electrons by polarized [sup 3]He are mainly those arising from the effective proton and neutron polarizations generated by the [ital S][prime] and [ital D] waves in [sup 3]He. A simple and reliable equation relating the neutron [ital g][sub 1][sup [ital n]], and [sup 3]He, [ital g][sub 1][sup 3], spin structure functions is proposed. It is shown that the measurment of the first moment of the [sup 3]He structure function can provide a significant check of the Bjorken sum rule.
