"NettetIt’s important to state that the energy is quantized and absorption of radiation causes a molecule to move to a higher internal energy level. This is achieved by the alternating electric field of the radiation interacting with the molecule and causing a change in the movement of the molecule. " - Interactions at the absorption level

NettetAbsorption One of the most fundamental light-matter interactions is the absorption of a photon that causes an electron to move up from its ground state to an excited state. The excited state could be virtual or a quantum level in a molecule depending on the energy of the photon and the difference between the energy levels in the molecule. diabetic blood sugar testing chartNettetWhen an atom absorbs an UV photon or a photon of visible light, the energy of that photon can excite one of that atom’s electrons to a higher energy level. This movement of an electron from a lower energy level to a higher energy level, or from a higher energy back down to a lower energy level, is known as a transition. cindy lawerence farmers insNettetQualitative evidence for absorption of 2,4-DNP after inhalation and/or dermal exposure is provided by reports of health effects in workers; however, the exposures may have included uptake by the oral route.
