En nomenclature, trois types de fusion sont connus : L'ortho-fusion et l'ortho- et péri-fusion, formant des systèmes polycycliques fusionnés ayant deux ou plus atomes en commun, et la spiro-fusion, qui engendre des composés spiraniques ayant un seul atome en commun. Il faut ainsi préciser la nature de la fusion, par exemple : composé hydroxylé à anneaux ortho-fusionnés, composé hydroxylé à anneaux ortho- et péri-fusionnés, ou composé hydroxylé à anneaux spiro-fusionnés. 1, record 1, French, - cycles%20fusionn%C3%A9s
