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 ...
The signatures of RDX, PETN, TNT and Tetryl were recorded both in the infrared and the THz domains, using Fourier transform infrared (FTIR) spectroscopy. Samples consisted of thin films and were made by depositing and subsequent evaporation of an acetone-explosive mixture. The complete spectrum ...
A detailed interpretation of the 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...
The following section shows the curing of a plastic adhesive. The adhesive is mainly made up of acetone, butyl acetate, and poly methyl methacrylate (PMMA). For the measurement, a small drop of the adhesive was placed on the diamond crystal of the ATR unit. A spectrum was then automatically...
The reduced mass is essentially the relative mass of the two sides of the oscillator – in a diatomic, the two atoms; in a polyatomic, the mass of the two sides of the bond. As the mass goes up, the frequency goes down. The Raman spectrum of carbon tetrachloride shows five bands at ...
Moreover, the IR spectrum of SnO2 film displays a broad peak around 3410 cm−1, indicating the presence of O–H on the film surface. The IR absorption spectrum is size- and morphology-dependent [28]. The film doped with 3.0% Ni shows more intensive absorption bands compared with the ...
