We report the X-ray absorption of isolated H3O+ cations at the O 1s edge. The molecular ions were prepared in a flowing afterglow ion source which was ... Hydronium is a cation that has a formula of H3O+. It often is made from a water molecule combined with a positively charged hydrogen ion. We report on Herschel/PACS observations of absorption lines of OH+, H2O+ and H3O+ in NGC 4418 and Arp 220. Excited lines of OH+ and H2O+ with E_lower of at ... R C N. R. Cl. C. O. MgBr then H3O+.
