Proton Magnetic Resonance Absorption in Cetyl Alcohol

Abstract
The line shape of the proton absorption in cetyl alcohol was studied with an autodyne receiver between room temperature and the melting point. The second moment was calculated from recorded derivative curves. The obtained second moment had a hysteresis effect. When the temperature was raised from room temperature, the second moment was almost constant of about 18.5 gauss 2 and it decreased abruptly to the value of 8 gauss 2 near the melting point. When the temperature was lowered from the melting point the second moment kept a small value till the transition point and then increased. The large second moment seems to be arisen from the monoclinic state and the small second moment from the hexagonal state. It was observed that the resonance line had a fine structure at its center.
