Let L be a nonnegative, self-adjoint operator on L2(ℝn) with the Gaussian upper bound on its heat kernel. As a generalization of the square Campanato space L2,λ-Δ(\mathbb Rn), in \citeDXY the quadratic Campanato space LL2,λ(ℝn) is defined by a variant of the maximal function associated with the semigroup \e-tL\t≥ 0. On the basis of \citeDX and \citeYY this paper addresses the preduality of LL2,λ(ℝn) through an induced atom (or molecular) decomposition. Even in the case L=-Δ the discovered predual result is new and natural.
