Photoexcitation<span> is the photoelectrochemical process of electron excitation by photon absorption, when the energy of the photon is too low to cause photoionization. The absorption of the photon takes place in accordance with Planck's quantum theory.</span>
<span>When looking to power your equipment or vehicle with natural gas. A lot of people use natural gas in their homes for cooking and heating, but they don’t really give it some thought.
