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. Semiconducting and conducting samples heat when ions or electrons withi… WebJan 10, 2014 · Microwave (MW) irradiation uses an electromagnetic field at a specific frequency in some way similar to that of photochemical-activated reactions.
