How are photons measured/calculated
WebG. Gauglitz, in Photochromism, 2003 3.3 Quantum yields. In preparative photochemistry the quantum yield usually is understood as the product yield of a reaction. It is calculated by the number of reacting moles of reactant per unit time. This type of quantum yield has been preferred, since it can be measured with small expenditure.
