摘要

Process for the selective dissociation of chemical compounds comprises exciting the selective excess energy regions of the electronic states of the compound to be dissociated, where completely or partially communicating rotational states are present in the excess energy regions. Preferred Features: The selective excitation is carried out with an energy lying below the dissociation energy, where the dissociation is carried out through a tunnel effect. The compounds are excited in the gas, liquid or solid phase using absorption electromagnetic waves, especially of light in the visible or infrared region. Excitation is carried out using a laser or mercury quartz lamp.
