FACTOID #151: The five countries with the highest coffee consumption are also the five countries whose citizens trust one another the most. Coincidence? Probably.
The energy levels of two or more physical states are said to be degenerate when they have the same value. In quantum theory, this usually pertains to electronic configurations and the electron energy levels, which can then, due to additional effects, undergoe splitting. In physics and quantum chemistry, an energy level is a quantized energy of a bound quantum mechanical state. ... The willingness to question previously held truths and search for new answers resulted in a period of major scientific advancements, now known as the Scientific Revolution. ... The word degeneracy has more than one meaning: In general, degeneracy means reverting to an earlier, simpler, state In mathematics, a limiting case in which a class of object changes its nature so as to belong to another, usually simpler, class. ... Fig. ... Electron configuration is the arrangement of electrons in an atom, molecule or other body. ... Properties The electron is a subatomic particle. ...
The energy difference between ground state and singlet oxygen is 94.2 kJ/mol and corresponds to a transition in the near-infrared at ~1270 nm.
It can be generated in a photosensitized process by energy transfer from dye molecules such as Rose Bengal, Methylene Blue or porphyrins, or by chemical processes such as spontaneous decomposition of hydrogen trioxide in water or the reaction of hydrogen peroxide with hypochlorite.
One of the roles of carotenoids in photosynthetic systems is to prevent damage caused by produced singlet oxygen by either removing excess light energy from chlorophyll molecules or quenching the singlet oxygen molecules directly.
