Decomposition of gaseous phthalic anhydride from a vibrationally hot molecule formed by ArF laser irradiation

ArF laser flash photolysis was used to study the photodecomposition of gaseous phthalic anhydride (PA). The experimental conditions (concentration of the ground-state PA, the inert gas pressure, and the laser fluence) strongly influenced the transient absorption profiles. Both biphenylene and triphenylene were detected as the final products. The results indicated that benzyne (1,3-cyclohexadien-5-yne) formation occurred during the photolysis. The quenching of biphenylene formation by a foreign gas showed that biphenylene was derived from a vibrationally excited (hot) intermediate. The hot PA, the vibrational temperature of which was 2700 K, and benzyne were determined to be intermediates of the PA decomposition reaction.
