Ir led strip can be done barbecue?

Infrared wave has longer lengths (radio, microwave, infrared, visible light. Wavelength  in order from  from long to short），the impression is feeling the heat, the effect is produced by thermal effects,
what kind of level is reach when then the infrared transmission? If the infrared can penetrate to theatomic, molecular internal, so will cause the atomic, molecular enlargement and can lead to the disintegration of atoms, molecules. This is really the case? As a matter of fact? Infrared frequency is low, the energy is not enough, the ir led could not achieve effect that atomic and molecular disintegration .
Therefore, the infrared can only penetrate the gap of the atoms and molecules, and can not penetrate to the internal of atoms, molecules. because the infrared can only penetrate into the interstitial of atoms, molecules, will cause the vibration of atoms and molecules to accelerate, distance to big,
increasing the thermal energy, from a macro perspective, the material in the melting and boiling in, on vaporization, but the nature of matter (atoms, molecules themselves) did not change,this is the infrared thermal effect. So we can use this infrared excitation mechanism to barbecue food, make organic polymer degeneration, but cannot use the infrared ray generated photoelectric effect, but can not make the nuclear internalchange.
