The effects of different solvents and of a change of temperature on the infrared band due to the fundamental hydroxyl stretching vibration in several 2,6-di-t-alkyl phenols and in the corresponding ortho-t-alkyl phenols have been examined. The conclusion that the two bands observed in ortho-t-alkyl phenols represent cis and trans isomers has been confirmed. The differences in enthalpy and entropy between the two isomers have been measured for six different phenols.
