The infrared frequencies, intensities, and half-band widths of the fundamental stretching vibration of the hydroxyl group have been measured for a large number of ortho-alkyl phenols. It has been found that phenols containing a single ortho-alkyl substituent exist as cis and trans isomers in unequal amounts, the trans isomer being the more abundant. The difference in free energy between the two isomers
已经测量了大量邻烷基苯酚的羟基基本伸缩振动的红外频率、强度和半带宽。已经发现含有单个邻烷基取代基的酚以不等量的顺式和反式异构体形式存在,反式异构体更为丰富。对于邻甲酚、2,3-二甲基苯酚和几种邻叔烷基苯酚,在 24 °C 的四氯化碳稀溶液中测量了两种异构体之间的自由能差异。
