oxygen groups attached to carbon such as carbonyl (CO), carboxyl (COOH), hydroxyl (COH), epoxy (COC) and a lot of water molecules, which can be quantitatively and qualitatively described by the XPS (from evaluation of the C 1s and O 1s XPS spectra) [23] and by the FTIR spectroscopy....
Raman spectra of the same samples given in Fig. 2(b) reveal the preferred phonon of 150 cm-1 which is an indication of anatase phase. The phonon frequency (wavenumber) position is however observed to change and shift to lower wavenumbers as demonstrated by a dotted line in Fig. 2(b)...
We compared the experimentally recorded FT-IR spectra and the theoretically simulated spectra (Figure 3). The internal coordinates of the compound have been presented in Table S3 (Supplementary). Further, the local symmetry coordinates, which are non-redundant, were represented in Table S4 (...
UV–visible spectra of sample solutions were recorded in 1 cm quartz cells at a scan speed of 40 nm·min−1. The absorbance and absorption maximum wavelength of PEDOTs, PEDOT_Naphs, PEDOT_SPAESs and SPAESs in their solutions of DMF, DMAc, DMSO, and NMP (concentration of 0.1% w/w)...
