“…For the title compound the DFT calculations give the υCH modes in RI at 2991 and 2983 cm -1 . Kasyan et al and Tarabara et al reported the υCH modes at 3080 cm -1 and 3070-3050 cm -1 for similar derivatives [47,31]. Most of the bands are not pure, but contains significant contributions from other modes.…”

“…In the present case, the νCN stretching modes to C13-N15, C16-N15, C19-N15, C31-N38 and C63-N47 are observed at 1347, 1151, 1121 cm -1 in the IR spectrum 1340, 1121 cm -1 in the Raman spectrum and at 1348, 1339, 1144, 1127, 1107 cm -1 theoretically. Kasyan reported the CN stretching in the region 1350-1100 cm -1 [47]. For bridging methylene groups, the CH2 (at C19, C28, C31, C63) vibrations are observed in the region of 3000-2800, 1400-1200, 1150-875 and 850-600 cm -1 [48].…”

1,7,8,9-tetrachloro-10,10-dimethoxy-4-[3-(4-benzylpiperazine-1-yl)propyl]-4-azatricyclo[5.2.1.02,6] dec-8-ene-3, 5-dione (TCDBPAD) have been calculated theoretically to obtain optimized geometry, vibrational frequencies and corresponding vibrational assignments. Charge transfer within the molecule was evaluated using HOMO and LUMO analysis. By hyper-conjugative interaction and charge delocalisation which can be analysed using NBO analysis, we can understand about the stability of the molecule. By using DFT method Molecular electrostatic potential (MEP) was calculated. First hyperpolarizability values are calculated in order to check the non-linear optical activity. Using MD simulations, we have visualized the ALIE and Fukui functions. The degradation property of compound in presence of water was evaluated using RDF curves. By solubility parameter we have identified suitable excipient for the title compound. Molecular docking studies proved that the title compound can be used for the treatment of Cardiovascular and Cerebrovascular diseases.

“…The literature extensively reported on reaction mechanisms that occur between the SAH groups or epoxy groups of the silanes with nylon NH 2 groups. − Hence, it is possible that the disappearance of NH/NH 2 signals is due to the consumption of these functional groups via chemical reactions. Scheme c and d show the possible reactions that occurred at the interfaces between the epoxy of γ-GPS with nylon and between the SAH of SAH silane with nylon.…”

Poly(dimethylsiloxane) (PDMS) has numerous excellent properties and is extensively used as the main component of many silicone products in a variety of research fields and practical applications such as biomedical materials, aviation, construction, electronic devices, and automobiles. Interfacial structures of PDMS and other components in silicone systems are important for such research and applications. It is difficult to probe interfacial molecular structures of buried solid−liquid and solid−solid interfaces of silicone materials due to the lack of appropriate analytical tools. In this feature article, we presented our research on elucidating the molecular structures of PDMS as well as other additives in silicone samples at buried interfaces in situ at the molecular level using a nonlinear optical spectroscopic technique, sum frequency generation (SFG) vibrational spectroscopy. SFG was applied to study various PDMS surfaces in liquid environments to understand their fouling-release and antifouling activities. SFG has also been used to study buried solid−solid interfaces between silicone adhesives and polymers, elucidating the molecular adhesion mechanisms. Our SFG studies provide important knowledge on interfacial structure−function relationships of silicone materials, helping the design and development of silicone materials with improved properties through optimization of silicone interfacial structures.

“…The 5-H and 6-H signals in the spectrum of XI are displaced to δ 3.12 and 3.05 ppm [11,22], and the anti-7-H signal appears at δ 0.76 ppm due to magnetically anisotropic effect of the exo-oriented epoxide ring on the proton in the methylene bridge located directly above the oxirane ring plane. The 5-H and 6-H signals in the spectrum of XI are displaced to δ 3.12 and 3.05 ppm [11,22], and the anti-7-H signal appears at δ 0.76 ppm due to magnetically anisotropic effect of the exo-oriented epoxide ring on the proton in the methylene bridge located directly above the oxirane ring plane.…”

“…Therefore, we were able to use criteria which were formulated previously while interpreting the 1 H NMR spectra of REACTIONS OF Bi-, Tri-, AND TETRACYCLIC AMINES stereoisomeric amines II and IV and their derivatives, such as sulfonamides, carboxamides, ureas, and amino alcohols [22]. Signals from the 2-H and 8-H protons (that are neighboring to the carbonyl group) in the spectra of bicyclic amido acids were displaced considerably downfield relative to their positions in the spectra of the initial amines.…”

Succinic anhydride reacted with cage-like amines {bicyclo[2.2.1]hept-5-en-exo-and -endo-2-ylmethanamines, 2-(bicyclo[2.2.1]hept-5-en-endo-2-yl)ethanamine, exo-5,6-epoxybicyclo[2.2.1]heptan-exo-2-ylmethanamine, tetracyclo[6.2.1.1 3,6 .0 2,7 ]dodec-9-en-endo-4-ylmethanamine, 1-(bicyclo[2.2.1]heptan-2-yl)ethanamine, and 4-azatricyclo[5.2.1.0 2,6 ]dec-8-ene} to give the corresponding amido acids having a cage-like fragment. The latter were converted into carboximides by the action of hexamethyldisilazane in boiling benzene in the presence of zinc(II) chloride and then into epoxy derivatives. The structure of the newly synthesized compounds was confirmed by IR and NMR spectroscopy.
