Microwave radiation water molecules
Web21 sep. 2024 · They have discrete rotational and vibrational (and electronic) states. Low-frequency radiation (microwave and far-infrared) cause transitions between rotational states: radiation is absorbed, but only at specific frequencies, because the states are separated by well-defined energies. We usually call this a "rotational absorption spectrum". WebThis is good! In other words, microwave radiation cannot alter the chemical structure of food components. More precisely, when heating food in a microwave, the radiation that …
