Abstract Using the monodromy technique proposed by Motl and Neitzke (Adv. Theor. Math. Phys. 7(2003)307), we investigate the analytic forms of the asymptotic quasinormal frequencies for the massless scalar perturbation in the Garfinkle--Horowitz--Strominger dilaton spacetime. We find that the real parts of the quasinormal frequencies are TH ln 3. This agrees with that of the quasinormal modes in the Schwarzschild spacetime. Our result implies that Hod’s conjecture about ln 3 is still valid for the black hole spacetime in the string theory.
