Investigation Of N-H Center Dot Center Dot Center Dot O Interactions In N-Monosubstituted Caproamide - Ether Systems: Ft-Ir And Ft-Nir Spectroscopic Study
JOURNAL OF MOLECULAR STRUCTURE(2019)
摘要
This paper reports FT-IR and FT-NIR spectroscopic study of hydrogen bonding between N-mono-substituted caproamides and different ethers (diethyl ether and tetrahydrofuran) in carbon tetrachloride. With increase in ether concentration increase in intensity of red-shifted band, and decrease of intensity of monomer band has been observed. The MIR and NIR spectroscopic characteristics for N-H center dot center dot center dot O hydrogen bonded complexes and also the equilibrium constants for 1:1 complex formation are given. Further, influence of structural differences of ethers on hydrogen bonding was investigated using Taft equation. Good correlation between logarithm of formation constants and Taft steric and inductive factors has been obtained only for tetrahydrofuran in MIR range. (C) 2018 Elsevier B.V. All rights reserved.
