Figure 4: Characterization of 3-α by high resolution mass spectrometry
From: Evidence for an oxygen evolving iron–oxo–cerium intermediate in iron-catalysed water oxidation
(a) CSI-HRMS spectrum of 2- α, recorded immediately after the oxidation of 1- α (1 mM) by CAN (3 mM). (b) CSI-HRMS spectrum obtained during the WO reaction, on the addition of 75 equiv. of CAN to 2- α. (c–e) CSI-HRMS features associated with 3- α obtained in H2O, D2O and H218O as solvent. Spectra were recorded by setting the nebulizer and dry gas temperature of the cryospray instrument to 25 °C.
