Microwave Chemistry: General Features and Applications

However, for their use in laboratory reactions, a frequency of 2.45 Ghz is preferred, since this frequency has the right penetration depth for laboratory reaction conditions. Beyond 30 Ghz, the microwave frequency range overlaps with the radio frequency range. The microwave electromagnetic

Microwave chemistry - Wikipedia

Microwave chemistry is the science of applying microwave radiation to chemical reactions. Microwaves act as high frequency electric fields and will generally heat any material containing mobile electric charges, such as polar molecules in a solvent or conducting ions in a solid.Polar solvents are heated as their component molecules are forced to rotate with the field and lose energy in collisions.
