    Radioactive isotopes ranging from 11 O to 28 O have also been characterized, all short-lived. The longest-lived radioisotope is 15 O with a half-life of 122.266(43) s, while the shortest-lived isotope is the unbound 11 O with a half-life of 198(12) yoctoseconds, though half-lives have not been measured for the unbound heavy isotopes 27 O and 28 ...

    4), [10] [11] carbon pentoxide (CO 5), [12] carbon hexoxide (CO 6) [13] and 1,2-dioxetanedione (C 2 O 4). [14] [15] Some of these reactive carbon oxides were detected within molecular clouds in the interstellar medium by rotational spectroscopy. [16] Many hypothetical oxocarbons have been studied by theoretical methods but have yet to be detected.
