Microwave-assisted synthesis :: Anton Paar Wiki

All domestic “kitchen” microwave ovens as well as commercially available dedicated microwave reactors for chemical synthesis operate at a frequency of 2.45 GHz (corresponding to a wavelength of 12.25 cm). As can be precisely calculated, the energy of microwave irradiation is too low to cleave molecular bonds. [7]
