This paper presents some of the new results on giant resonances obtained using heavy ion projectiles. It is shown that the microscopic structure of giant states can be probed using γ coincidence measurements. An example of the search for high lying states with light "heavy ion" probes at high incident energy is given and, the investigation of multiphonon excitation using heavier ions at intermediate energy is discussed. These experimental results are compared with the theoretical predictions of the multiphonon model. The role of giant resonances in heavy ion reactions is discussed and in the light of the new experimental results the importance of the multiphonon excitation for the heavy ion dynamics is emphasized.
