Nan nonmen an nan bag spiro miltip, premye nimewo a nan parantèz endike atòm nan nan premye bag ki pi pre atòm Spiro a se nimewo a yon sèl. Nimewo ki rete yo reprezante kantite atòm ant atòm Spiro yo, oswa atòm yo nan bag tèminal la. Chak nimewo separe pa yon peryòd (peryòd angle). Nan egzanp sa a, gen de atòm (konte 1 ak 2) anvan spiroatom an premye (3). Pa gen atòm ant Spiroatoms 3 ak 4, ak menm bagay la tou pou verifye spiroatoms nan 4 ak 5, 5 ak 6. Gen de atòm sou bag an dezyèm tèminal, 6 ak 5, 5 ak 4, e gen youn ant 4 ak 3.

In the naming of multiple spiro rings, the first number in parentheses indicates that the atom in the first ring closest to the spiro atom is the number one. The remaining numbers represent the number of atoms between the spiro atoms, or the atoms in the terminal ring. Each number is separated by a period (English period). In this example, there are two atoms (numbered 1 and 2) before the first spiroatom(3). There are no atoms between 3 and 4 spiroatoms, and the same is true for spiroatoms at 4 and 5, 5 and 6. There are two atoms on the second terminal ring, 6 and 5, 5 and 4, and there is one between 4 and 3.
