Abstract
The emitted ultraviolet and visible radiation of a nitromethane flame has been investigated applying fast spectrometry. The measured spectra of the diatomic molecules OH, CN and NH were used for temperature determination (mean values OH:2400 K, NH:2300 K). The CN radical showed an exaggered value of about 4300 K, which is probably based on a non-thermal exitation. The high intensity of the OH emission allowed to determine an axial temperature profile. Intensity profiles of the emitting radicals and observed continuous radiation have been recorded to obtain a better characterization of the combustion.
