Abstract

A method for the infrared-light-induced yield optimization of chemical reactions is provided. An energy input into at least one starting material that is subjected to a chemical reaction takes place by means of infrared light pulses having a mean wavelength in the range of 2000 to 100000 nm. The chemical reaction here is a reaction in which a product, the molecular formula of which does not correspond to the molecular formula of the starting material, is formed and wherein the yield optimization for the most part is not based on a thermal heating of the starting material. The infrared light pulses have a fixed wavelength and the energy input into the starting material takes place by means of vibration excitation by a one-photon process.
