This paper reports on the results of positron annihilation lifetime measurements of three organic liquids: benzene (C6H6), cyclohexane (C6H12), and methanol (CH3OH). The lifetime spectra are acquired at different temperatures for non-degassed, degassed, and oxygen-saturated samples, at temperatures between 5°C and 25°C. The spectra are analyzed using a standard three-exponential model. The influence of oxygen on each lifetime and intensity component is discussed.
