The q-dependent magnetic susceptibility for disordered Ising and classical Heisenberg chains is calculated. The coupling between spins is of the form J(n)=J0e-β(n-1), β>0, with n the random number of interatomic units between neighboring spins. The cases where J is ferromagnetic or antiferromagnetic or of spin-glass type are examined.
