New study refutes light energy transfer theory

Chemist Heinz Langhals experimentally refuted the generally accepted theory of the transfer of light energy using

synthesis of test molecules.He showed that energy is actually transferred through molecular vibrations, just as the floor of a stage can transmit the vibrations of a piano to a cello standing on a platform. This process can be nanoscale, so the scientist is confident that its discovery will be especially useful for the further development of optical technologies.

When light meets matter, such assunlight that falls on the surface of the Earth - it is mostly absorbed and quickly converted into heat. However, in some cases, light energy is also transferred between molecular structures. For example, when a pigment excited by light transfers energy to another pigment. An example of this process is photosynthesis.

In numerous technological developmentsthis energy transfer is used. The theory of this process was developed 70 years ago by the physicist-chemist Theodor Förster. According to Förster Resonant Energy Transfer (FRET), light energy is transmitted without radiation via resonance through small molecular dipole antennas, i.e. via electromagnetic interactions. However, the new study is changing the scientific community's understanding of this process.
