Abstract: Rotational temperatures of CH* species present in ethanol flames with different diluent gas compositions were determined using natural emission spectroscopy. Spectrum fine-structures showed two different rotational temperatures. The results of A symmetry levels were slightly higher than A' for all flames investigated. The temperature values also indicated a non-equilibrium distribution.
Temperaturas rotacionais de CH* em chamas de etanol com diferentes gases diluentes foram determinadas por emissão natural. Estruturas finas do espectro indicaram duas temperaturas rotacionais. Os resultados dos níveis de simetria A foram ligeiramente maiores que os A'. Os valores também indicaram uma distribuição fora de equilíbrio.
