In the C 1s spectra (Figure S14c, Supporting Information), the content of the C═O peak decreases with the appearance of C─O peak, showing an n-type reaction during the discharge process. The XPS spectra of O 1s also exhibit a commensurate peak shift at 532.2eV (Figure S14d, Supporting Information).

The carbonyl stretching vibration band C=O of saturated aliphatic ketones appears at 1715 cm -1. Conjugation of the carbonyl group with carbon-carbon double bonds or phenyl groups, as in alpha, beta-unsaturated aldehydes and benzaldehyde, shifts this band to lower wavenumbers, 1685-1666 cm -1. See also:The peaks between 300 and 400 nm are usually ascribed to the n-π∗ transition of the C O or C N bond although this is attributed to peaks below 300 nm in some cases [33]. It is interesting to note that Y-CDs do not possess much discernible absorption in this region indicating the first difference between the CDs.

If you look at an IR spectrum of 1-butanol, you will see: there are sp 3 C-H stretching and CH 2 bending modes at 2900 and 1500 cm-1.; there is a strong C-O stretching mode near 1000 cm-1.; there is a very large peak around 3400 cm-1.O-H peaks are usually very broad like this one. who hosts In general, C-O stretching peaks are intense and normally fall between 1300 and 1000 cm-1 (going forward assume all peak positions are in cm-1 units). Because this wavenumber range is in the fingerprint region (2) there are often many peaks present between 1300 and 1000, but again the distinguishing feature of C-O stretches will be their intensity.The presence of these peaks agrees with the XPS results, which indicated the presence of only C, N and O.
