【摘要】 比较两对芳基糖苷端差异构体的傅里叶红外光谱图,证实了前人所归属的α和β糖苷键的特征吸收。并在1350cm^-1—1370cm^-1和1000cm^-1—1100cm^-1区域内,找到了α和β糖苷健的特征吸收,为用红外光谱分辨芳基糖苷端差异构体提供一个依据。更多还原

【Abstract】 The FT-IR spectra of some per-o-acetyl 2, 4-dinitrophenyl D-glycopyranoside anomers and D-galactopyranoside anomers were studied. By comparing the spectra of a anomer and β anomer, it was found that in the range of 1000cm^-1—1100cm^-1 and 1350cm^-1—1370cm^-1, the absorption frequencies of the two anomers are different, which can be used to distinguish one from the other.更多还原
