Laser desorption mass spectrometry is used to study thin films of purified La@C82. The films are changed on exposure to atmosphere due to oxidation reactions with molecular oxygen. The endohedral fullerene oxides fragment more readily on laser desorption leading to the formation of small lanthanum carbide species and LaO. The half life of the oxidation reaction is found to be on the order of a few days.
