WebFeb 1, 2024 · In FTIR analysis, due to the different peak positions of each bond of the various functional groups, redshift occurs (Table 2). Due to the existence of bond energy and repulsive force, the determination of an N-functional group is easily affected by other atoms or other functional groups, thus resulting in some deviation. WebThe crystal structure of 2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaiso-wurtzitane (CL-20) p-xylene solvate, and the solvent effects on the crystal faces of CL-20 were studied through a combined experimental and theoretical method. The properties were analyzed by thermogravimetry-differential scanning calorimetry (TG-DSC), Fourier transform infrared …

When IR radiation is passed through a sample, some radiation is absorbed by the sample and some passes through (is transmitted). The resulting signal at the detector is a spectrum representing a molecular ‘fingerprint’ of the sample.
