摘要
The compound N,N-bis(3,5-dimethyl-2-hydroxybenzyl) methylamine is synthesized to model the phenolic resulting from ring opening polymerization of benzoxazine monomers. Fundamental vibrational assignments of N,N-bis(3,5-dimethyl-2-hydroxybenzyl)met are made by the analysis of the fingerprint region (2000-500 cm(-1)) of the infrared and Raman spectra of crystalline, quenched, and molten dimers. In addition, the hydrogens in the methylene bridge structure are deuterated to provide insight into vibrations due to the presence of the bridge structure. The structure of hydrogenated and deuterated model dimers is verified by H-1 and C-13 nuclear magnetic resonance spectroscopy.
