To understand the fundamental mechanism of how light absorption is converted into the thermal energy. the atomic motion of matters are studied using the quantum molecular dynamics method. As the fundamental atomic system, several metallic atoms are considered to be irradiated with light by changing the frequency and intensity. Under infrared light irradiation, the increase in the kinetic energy and atomic dissociation are attributed mainly to the dipole moment fluctuations of ions. Under the irradiaiton of light at electron energy levels, the change in the kinetic energy and dissociation are resulted from the change in the potential energy between particles due to electron excitation. This mechanism causes the characteristic difference in the kind of fragments and atomic motion under various light irradiation.
