The thermal isomerization of azulene was studied in shock waves over the range 1300–1900 K. Monitoring azulene and naphthalene light absorptions in the UV, a complete conversion azulene → naphthalene was observed. After correction for some falloff effects, a limiting high pressure rate constant k x = 10 12.93 exp(−263 kJ mol −1 /RT) s −1 was derived. Based on this k x , specific rate constants k ( E ) for photoexcitation experiments were constructed.
