Spatially resolved chemiluminescent spectra were obtained in the reaction zone in a laminar premixed methane/air and propane/air flame (φ = 0.9-1.5) using local flame emission measurements with a new Cassegrain optics and spectrometers. Highly spectrally resolved OH^*, CH^* and C^*_2 emission were obtained at the local flame front in both methane and propane. Detailed structure of methane spectra and propane spectra were corresponding each other very well. The linear correlations between the peak intensity rations of OH^*/CH^*, C^*_2/CH^*, and C^*_2/OH^* to the equivalence ratio were estimated using the power fitting of y = A×x^B in experimentally. These functions could be applicable to the prediction of local stoicheometry in hydrocarbon flames. Futhermore, chemiluminescnecne spectra dependence on temperature were examined and it was found that spectral structure less depended on temperature.
