Concentration time-histories were measured behind reflected shock waves during n-heptane oxidation for five species: n-heptane, C(2)H(4), OH, CO(2), and H(2)O. Experiments were conducted at temperatures of 1300-1600 K and a pressure of 2 atm using a mixture of 300 ppm n-heptane and 3300 ppm oxygen (phi = 1) in argon. n-Heptane and ethylene were monitored using IR gas laser absorption at 3.39 and 10.53 mu m, respectively; OH was monitored using UV laser absorption at 306.5 nm; and CO(2) and H(2)O were monitored using tunable IR diode laser absorption at 2.7 and 2.5 mu m, respectively. These time-histories provide kinetic targets to test and refine large reaction mechanisms for n-heptane and demonstrate the potential of this type of data for validation of large reaction mechanisms. Comparisons are made with the predictions of several recently developed reaction mechanisms.
