摘要
The FT-IR ( from 50 to - 180 degrees C) and the FT-Raman spectra at 25 degrees C of glutarimide in iu the solid state are investigated. The data are compared with recent results of Bienko et al.( J.Phys.Chem.A 101,7834 (1997) on glutarimide isolated in a low-temperature argon matrix. The vibrational changes induced by hydrogen bond formation in the crystalline state are discussed. The v(NH...O) vibration is observed at 3189 cm(-1) at 25 degrees C and at 3163 cm(-1) at - 180 degrees C. These values correspond to a contraction of the N...O distance of 0.022 Angstrom.
