This study addresses emission spectra of Air-ethanol and Air-kerosene flames by using optical multichannel analysis system (OMA). Experimental results show that there are several bands of molecular spectrum in a range from 275 to 600nm. Among them, the OH A2+X2r(300330 nm), the CH A2X2(410440 nm), and C2 A3gX3u (500 520 nm) emissions have the strongest intensity. In turn, the fine structures of OH (A2+X2r) and CH (A2X2) emission are studied by using a high resolution grating in experiment, and the distributions of spectra intensity are calculated at different rotational and vibrational temperatures based on the molecular spectroscopy. Moreover, by comparing the simulated spectra with the experimental spectra of OH (A2+X2r) and CH (A2X2) emissions, the rotational and the vibrational temperatures of Air-ethanol flame are determined in this paper.
