es Method and apparatus for excitation of resonances in molecules By www.freepatentsonline.com Published On :: Tue, 16 Sep 2014 08:00:00 EDT A method is described to excite molecules at their natural resonance frequencies with sufficient energy to break or form chemical bonds using electromagnetic radiation in the radio frequency (RF) and microwave frequency range. Liquid, solid, or gaseous materials are prepared and injected into a resonant structure where they are bombarded with electromagnetic energy in the RF or microwave range at resonant frequencies of the molecules of the materials. Alternatively, electromagnetic energy tuned to dielectric particles prepared from the materials may also be supplied to further enhance the reaction. Full Article
