We propose a direct numerical method to calculate the dynamical susceptibility, χ''(ω), in strongly fluctuating quantum systems, where the system is nonmagnetic but the exchange effect is very strong. We demonstrate this method by calculating ESR line shape χ''(ω) of the one dimensional antiferromagnetic Heisenberg model ( S =1/2) and comparing the results with those obtained by other methods and experiments.
