Single crystal structure determination using synchrotron X
... TFE is known to be a weak acid and to donate a hydrogen bond, comparable to that of phenol, and a 1:1 complex of TFE and pyridine as an acid-base pair is reported. Therefore, we expected that the dissociated pyridyl moiety from the metal ion center would be stabilized by the strong hydrogen bond of ...

In Situ Soft X‑ray Absorption Spectroscopy Applied to Solid
... since the absorption peak of EtOH is observed in the energy region higher than 286.4 eV (Figure 1a), the fitting analyses have been carried out in the energy region from 284 to 286.4 eV. As a result, all of the in situ spectra, except for the energy scans of the in situ N K-edge XAS from 84 to 120 mi ...
