Pauling曾研究过邻苯二酚之分子内氢键,并用共振论解释了第一倍频区的红外光谱,但没有给出氢键强度。最近有人测定过邻苯二酚的核磁共振谱,但给出的化学位移实验值误差太大。我们根据邻苯二酚之四氯化碳稀溶液在超导核磁共振仪上的实验结果,探讨了氢键位移、氢键强度和交换速率等信息。 Pauling has studied the intramolecular hydrogen bonding of catechol and used resonance theory to explain the infrared spectrum of the first frequency-doubling region, but did not give the hydrogen bond strength. Nuclear magnetic resonance spectra of catechol have been measured recently, but experimental errors in chemical shifts are too large. Based on the experimental results of CTC solution of Catechol on the superconducting NMR, we discussed the hydrogen bond shift, hydrogen bond strength and exchange rate.
