Species (chemistry)
As a species in a chemical context (engl. Species or chemical species ) refers to a specific kind of particles ( atoms , molecules or the like). Conformations , dissociation or redox levels etc. of the same substance, which are in equilibrium with one another and cannot be differentiated on the time scale of the reaction or measurement under consideration, belong to the same species. Where it does not matter, isotopes are not differentiated either.
Species is often used as a generic term when in a situation particle types are to be addressed together for which more specific names are otherwise common, such as molecules and ions , atoms and clusters or quasiparticles and color centers .
The formation of different species from one substance is called speciation . Examples of the extraction and determination of chemical species in solutions can be found in many chemistry textbooks or e.g. B. in web sciences .
