The paired IR and Raman spectra provide illustrated examples of the characteristic functional groups discussed in Chapter 6. The experimental conditions and sample preparation used for both the IR and Raman spectra are listed.Access through your organization Check access to the full text by signing ...
Spectroscopic control is performed with the aid of an auxiliary adsorbent, which is transparent in the infrared region of the spectrum and has hydroxyl groups on its surface. This method can be employed to determine the content of functional groups, capable of deuterium exchange, on the surface ...
aFunctional groups exhibited by uncoated Fe3O4, PVTri, and PVTri–Fe3O4 nanocomposite are investigated by FT-IR spectroscopy and the resultant spectra are presented in Fig. 3. 未上漆的磁铁矿、PVTri和PVTri磁铁矿nanocomposite陈列的功能小组由FT-IR分光学调查,并且总值光谱被提出在。 3. [translate...

The average accuracy rate of correctly identifying the functional groups of interest is 92.5% on our testing data. All the IR spectra of 632 organic molecules are from National Institute of Standards and Technology (NIST) database as the training set and are assessed. Results from this work ...
In case of the vibrational spectra, the position but even more the intensities depend strongly on the kind of halogen substituent. 展开 关键词: 2-Azetidinone β-Lactam Chirality DFT IR Raman Vibrational circular dichroism DOI: 10.1016/S0022-2860(03)00121-2 被引量: 10 年份: 2003 ...
(P = O) frequencies. They usually concentrated around 1241 cm−1on the FT-IR spectrum. These absorption bands are better observed in TS-Ph and SMS-Ph samples. Other main groups of observable absorption bands in the most IR spectra are related to the H2O related frequencies. The ...
The FT-IR spectra of COOH-CNT and COOH-Ph-CNT suggested that carboxylic groups are present on the CNTs (Fig. 2). The peaks at 1640 cm−1 and 1560 cm−1 were assigned to the ester groups CO and -C-O-C-stretching, respectively. A broad peak at around 3410 cm−1 can be ...
Herein, comprehensive characterizations including in situ Fourier-transform infrared (FT-IR) spectra, together with in situ electrochemical impedance spectroscopy (EIS) were employed to correlate the oxygen functional group types/contents with K+storage in GO. These functional groups remarkably expand the...
