We find that the position of infinite discontinuities of the heat capacities can be reflected in quasinormal spectrum. This shows the possible non-trivial relation between the thermodynamical and dynamical properties of black holes.revised version, accepted for publication in Phys.Lett.BHigh Energy Physics - TheoryGeneral Relativity and Quantum Cosmologytext
