Isotopomers of isotopically modified ethanol. The molecule at the bottom left is not an isotopomer of any other depicted molecule. Isotopomers or isotopic isomers are isomers which differ by isotopic substitution, and which have the same number of atoms of each isotope but in a different arrangement.
Atropisomers are conformational isomers which can be separated due to restricted rotation. [18] The equilibrium between conformational isomers can be observed using a variety of spectroscopic techniques. [19] Protein folding also generates conformers which can be observed.
