不要得到太附有任何人,因为附件导致期望,并且期望导致失望。[translate] aIn order to investigate chemical bond or functional groups of the as-prepared PTh, the FT-IR spectrum was employed. 为了调查化学键或和准备的PTh的功能小组, FT-IR光谱被使用。[translate]...
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 ...

The fitted curve of the FTIR spectrum ranging from 3000 to 3600 cm−1is shown in Fig.7. The range of 3050–3150 cm−1belonged to the aromatic C–H stretching, the value of 3200 cm−1belonged to the ring hydrogen bond, the range of 3300–3315 cm−1belonged to the OH⋯OR, ...
groups of IR absorption bands which are related to the νas(Si–O–Si) frequencies. The P-containing groups were induced a new group of absorption band which are related to ν(P = O) frequencies. They usually concentrated around 1241 cm−1on the FT-IR spectrum. These absorption ...
(PFHMS).Its application performance on cotton fabric was investigated.The chemical structure of PFSEAS was characterized by infrared spectrum(IR) and proton nuclear magnetic resonance(1H NMR).The film morphology of PFSEAS on cotton fiber surfaces was observed by field emitting scanning electronic ...
of the similar absorption frequencies for those groups in different molecules. The actual frequency is affected by the environment, so the reference chart shows wide bands rather than specific frequencies. The identification of functional groups is a cornerstone of IR spectroscopy and organic chemist...
The digital difference spectrum technique in X-ray photoelectron spectroscopy has proved to be effective for the analysis of the functional groups introduced by surface oxidation treatment of carbon fibers. The major functional groups introduced to the carbon fiber surface by surface oxidation are hydroxy...
Roughly speaking, the preparation method of the well-defined sample of the star polymer can be classified into two; the reaction of the living polyanion 'with a suitable linking agent having several reactive groups, and the initiation· of the living anionic polymerization by using a ...
