In order to analyze the difference between the inverse diffusion flame (IDF) and normal diffusion flame (NDF) under various conditions, the emission spectra of OH* and CH* chemiluminescence in two dimensions measured by hyperspectral and ultraviolet (UV) cameras are described in this article. The results show that CH* mainly appears in the fuel side near the flame front, while OH* distribution can reflect the reaction region of flame. According to the OH* radial distributions in IDF and NDF, the flame can be divided into three parts: the core area of the flame, the transition region of the flame, and the developed region of flame. The peak intensity of CH* in IDF is higher than that in NDF. Moreover, the length of reaction region in NDF increases with O/C equivalence ratio ([O/C]e) until it reaches a steady value, while in IDF the length decreased with the increase of [O/C]e.
