When O3 dispersed in a solid CO2 matrix, or a mixture of O3 and CO2 dispersed in solid argon is photolyzed using ultraviolet light, O3 disappears and a new substance forms. This substance shows infrared-absorption maxima at 2053, 1894, 1070, 975, and 564 cm−1. These absorption bands are ascribed to CO3. The molecule CO3 is capable of reacting with O2 to form O3. Experiments using 18O-labeled CO2 show that the oxygen in O3 formed by the reaction of O2 with CO3 is in part derived from the CO2.
A binuclear ion ([NH(3))5RuN(2)Ru(NH(3))(5)](5)+ is formed by the direct reaction of N(2) with an aqueous solution of (NH(3))(5)RuOH(2)(2+) at room temperature. The binuclear ion is also formed by the reversible reaction of (NH(3))5RuOH(2)(2+) with (NH(3))(5)RuN(2)(2+). Solid [(NH(3))(5)RuN(2)Ru(NH(3))(5)] (BF(4))(4) has been prepared, and its ultraviolet and infrared spectra are reported.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
