结论甲基拉伸基频在2850 ~ 3000 cm”1范围内变化，这取决于甲基取代的性质。该波段的强度通常较弱，也受取代基的影响。对甲基伸展基的鉴定最好是通过对其相邻的甲基（当有一个甲基时）进行氘化。由于在这里考虑的各种分子中，甲基拉伸基本原理的频率和强度的显著变化，氘化实验对于可靠地确定其他分子中的甲基拉伸基本原理似乎是必不可少的。这项工作得到了NIH （GM29375）和范德比尔特大学的资助。
ConclusionsThe methine stretching fundamental frequency varies in the range of 2850-3000 cm" 1, depending upon the nature of substitution at the methine group. The intensity of this band is usually weak and is also influenced by the substituent. Identificationof the methine stretching fundamental is better done by deuteriation of the methyl group adjacent to it (when there is one). Because of the significant changes in frequency and intensity of the methine stretching fundamental, in the various molecules consideredhere, deuteriation experiments appear indispensable for reliable as-signment of methine stretching fundamentals in other molecules.Acknowledgment.
