Photoionization is the process in which an atom or molecule absorbs a photon and subsequently loses an electron, resulting in the formation of a positively charged ion. This phenomenon typically occurs when the energy of the incoming photon exceeds the ionization energy of the atom or molecule. Photoionization plays a critical role in various fields, including astrophysics, atmospheric chemistry, and mass spectrometry, as it helps to understand the behavior of matter under different energy conditions.
V S Letokhov is a Russian physicist known for his work in the field of laser spectroscopy and quantum optics. He has written numerous research articles and papers on topics related to laser physics, quantum optics, and spectroscopy. Letokhov's work has significantly contributed to the development of these areas of physics.

One possible molecule formed by photoionization is a molecular ion, such as H2+ (hydrogen ion). This process occurs when a molecule absorbs a photon with enough energy to remove an electron, resulting in the formation of a positively charged ion.
Isopropanol concentrations in air can be measured using a gas detector or a direct-reading instrument equipped with a photoionization detector (PID). The PID measures the concentration of volatile organic compounds (VOCs), including isopropanol, in parts per million (ppm) by ionizing the compounds and measuring the resulting electric current. Regular calibration and maintenance of the instrument are necessary for accurate measurements.
When a photon is absorbed by an atom, it can excite an electron to a higher energy level or even ionize the atom by completely removing an electron. This absorption of energy can cause the atom to undergo various processes such as fluorescence, photoelectric effect, or photoionization, depending on the energy of the photon and the characteristics of the atom.
Well maybe because there has been some reports on people dying cause of the gas inhaled and the Carbon Dioxide is bad to inhale coming from plants and all.first of all from my own opinion u need to know the type of bonding exibited by carbondioxide. but since CO2 is covalent, it will be very difficult for it to be ionised except it dissolve in water.
Yes. Infrared are currently considered to be the best option to detect gas leaks. They use the absorption of infrared radiation at certain wavelengths to detect dangerous levels of toxic and combustible gases.
