Oxygen 124-130 spindlin 1 Homo sapiens 44-48 14995343-1 2004 We report the first direct observation of the oxygen-isotope ((16)O/(18)O) effect on the in-plane penetration depth lambda(ab) in a nearly optimally doped YBa(2)Cu(3)O(7-delta) film using the novel low-energy muon-spin rotation technique. Oxygen 46-52 spindlin 1 Homo sapiens 214-218 12477933-7 2002 The slower phases of O2 recombination can be explained by the presence of two higher spin states, S = 2 and S = 3, which have a small and relatively large barrier to ligand recombination, respectively. Oxygen 21-23 spindlin 1 Homo sapiens 85-89 11084289-10 2000 In the presence of oxygen a different species was observed with DEPMPO, DPPMPO, and DBPMPO, which was only slightly suppressed upon the addition of SOD, possibly the respective spin adduct of either the alkylperoxyl radical or, in analogy to DMPO, a secondary alkoxyl radical. Oxygen 19-25 spindlin 1 Homo sapiens 177-181 11890791-0 2002 Spin surface crossing in chromium-mediated olefin epoxidation with O(2). Oxygen 67-71 spindlin 1 Homo sapiens 0-4
