Spatially resolved chemiluminescent spectra were obtained in the reaction zone in a laminar premixed methane/air flame (φ 0.9-1.5) using local flame emission measurements with a new Cassegrain mirror system and spectrometers. The linear correlations between the peak intensity ratios of OH^*/CH^*. C_2^*/CH^*, and C_2^*/OH^* in the reaction zone to the equivalence ratio could be used to investigate the local flame stoichiometry. Local chemiluminescence measurements of OH^*, CH^* and C_2^* were also carried out at the flame front of premixed turbulent propane/air flames to study details of the reaction zone and flame-front structure. The structure of the flame front can be characterized by the local Damkoler number.
