Heats of formation of 50 and 53 kcal mol-' have been measured for pand o-xylylene by using pulsed-ion cyclotron double-resonance spectroscopy. In addition a lower bound of 76 kcal mol-' has been obtained for the heat of formation of gaseous m-xylylene. The family of C6H6 hydrocarbons comprises a variety of interesting and much studied compounds, ranging in stability from styrene to the highly strained
