Using recently derived relations between spin-dependent nuclear and nucleon g(1) and g(2) structure functions at finite Q(2), we study nuclear effects in He-3 in the nucleon resonance and deep inelastic regions. Comparing the finite-Q(2) results with the standard convolution formulas obtained in the large-Q(2) limit, we find significant broadening of the effective nucleon momentum distribution functions, leading to additional suppression of the nuclear g(1) and g(2) structure functions around the resonance peaks.
