本文测定了 FN-n,FE-n,FNE-n 和 FM-n 四个系列的核磁共振谱及红外光谱.核磁共振谱中,α氢的吸收峰在最高场,而β氢的吸收峰在最低场.随着共轭链的增长,α,β氢的吸收峰都向高扬移动.它们的化学位移与结构之间的关系近似地遵循同系线性规律.和核磁共振相似,红外光谱的 c=c,c=o 伸缩振动频率和结构之间的关系也近似地遵循同系线性规律.
In this paper, the nuclear magnetic resonance spectra and infrared spectra of four series of FN-n, FE-n, FNE-n and FM-n were measured.Nuclear magnetic resonance spectra showed that the absorption peak of α-hydrogen was in the highest field and the absorption peak of β- The lowest field.With the increase of the conjugate chain, the absorption peaks ofα, βhydrogen move upwards.The relation between their chemical shifts and the structure approximately follows the homology linear law.Compared with the nuclear magnetic resonance, c = c, c = o The relationship between the stretching vibration frequency and the structure also follows the homology linear law approximately.
