Chemical species

A species is 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 each other and can not be distinguished on the time scale of the observed response or measurement belong to the same species. Where it does not need it, even isotopes are not distinguished.

Species is often used as an umbrella term, if particle species to be addressed jointly in a situation for the other specific names are common, such as molecules and ions, atoms and clusters or quasi-particles and color centers.

The formation of different species from a substance called speciation.
