Editing Ozone (section)

==Structure==
According to experimental evidence from [[microwave spectroscopy]], ozone is a bent molecule, with C<sub>2v</sub> [[molecular symmetry|symmetry]] (similar to the [[water]] molecule).<ref>{{cite web |title=Microwave Rotational Spectroscopy |date=2013-10-02 |language=en |website=Chemistry LibreTexts |url=https://chem.libretexts.org/Bookshelves/Physical_and_Theoretical_Chemistry_Textbook_Maps/Supplemental_Modules_(Physical_and_Theoretical_Chemistry)/Spectroscopy/Rotational_Spectroscopy/Microwave_Rotational_Spectroscopy |access-date=2022-07-13}}</ref> The O–O distances are {{convert|127.2|pm|Å|abbr=on|lk=on}}.

The arrangement possesses an overall [[bond order]] of 1.5 for both sides. It is [[isoelectronicity|isoelectronic]] with [[nitrite|the nitrite anion]]. Naturally occurring ozone can be composed of substituted isotopes (<sup>16</sup>O, <sup>17</sup>O, <sup>18</sup>O). A [[cyclic ozone|cyclic form]] has been predicted but not observed.
