Popis:	By employing the Fourier transform method, the internally referenced chemical shifts of the protons of absolute ethanol at temperatures between -83 and 120°C and pressures up to 5 kbar have been measured. Corresponding densities of absolute ethanol between 23 and 120°C are also reported for pressures up to 4 kbar. A substantial portion of the temperature shift of the hydroxyl proton is found to be due to density variation. An essentially linear change of the hydroxyl shift with density at five constant temperatures can be described by an empirical equation valid only for liquid ethanol relating the relative chemical shift of the hydroxyl proton to temperature and density.
