For example, it is common to observe the sharp feature (orspike assigned to the Q-branch of the vibrational–rotationalspectrum, as indicated by the vapor spectrum of acetone (Figure1. If we proceed up the homologous series from methane (CH4 to n -hexane (C6H 14, there are 20component ...

IR Spectroscopy is a Term used to refer to Infrared Spectroscopy which deals with the Infrared Region of the Electromagnetic Spectrum. Learn more about IR spectroscopy here.
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 ...
IR spectrum of methyl-3,4-anhydro-α-D-talohexopyranoside that is based on complete calculation of normal vibration frequencies and absolute IR absorption band intensities of the molecule and a comparison of the results obtained with the corresponding experimental data is given for the first time....
Samples consisted of thin films and were made by depositing and subsequent evaporation of an acetone-explosive mixture. The complete spectrum spanned the range from 4,000 to 8 cm~(-1) at 2.0 cm~(-1) spectral resolution. Preliminary results in the infrared agree with those of previous ...
To clarify why the molecular distribution became more stable, we further explored the change of the bottom ZnO and Ir/IrOxwith removing the BHJ films. Comparing with theO 1 score-level XPS spectrum of the fresh ZnO film, the ratio of O-vacancy increases in the aged ZnO film (Fig.5aand...
Abstract Both near-infrared (NIR) and mid-infrared (mid-IR) spectroscopies are extremely important techniques for polymer analysis because of their sensitivity and versatility. The basic difference between NIR and mid-IR spectroscopies is that bands in the mid-IR region, 400–4000 cm−1, are ...
Doping other transition metals to enhance the photocatalytic activity of TiO2TiO2 is one of the solutions, making M-doped TiO2TiO2 (M: other metals) photocatalysts for treating some toxic gases. In 2011, Ming Jin et al. developed the W-doped TiO2TiO2 photocatalyst to decompose acetone with a ...
