isomerization

https://doi.org/10.1351/goldbook.I03295
A chemical reaction, the principal product of which is @I03291@ with the principal reactant. An @I03130@ isomerization that involves the breaking or making of bonds is a special case of a @M03997@. Isomerization does not necessarily imply @M03997@ (e.g. in the case of the interconversion of conformational isomers).
