The typical behavior of the liquid mixture studied is explained on the basis of the CH, NH, CN bond stretching. The molecular interaction and intermolecular hydrogen bonding has been examined from the recorded FTIR spectra. Available thermal energy changes the strength of bonds among the molecules ...

The band at 3005 cm−1 was due to stretching vibrations of the cis olefinic double bond. Lard has the more quantity of oleic and linoleic acyl group alternated to other fats due to the higher frequency for this band as depicted in Fig1(C). Both the methylene asymmetrical stretching ...
Similar results were obtained for the weaker HCl and H2O complexes. Three bond stretching modes were observed for the N2‐‐H–F‐‐H–F complex. 展开 关键词: Chemical bonds Complex solids Fourier transform infrared spectroscopy DOI: 10.1063/1.449763 ...
The enthalpy and the entropy of hydrogen bond dissociation are also obtained as 9.6 kJ mol 1 and 44.8 J mol 1 K 1 , respectively. Two CC in‐plane vibrational bands of the aromatic rings at 1614 and 1598 cm 1 were studied at different temperatures. The integrated absorbance for both ...
