STUDY ON SPECTRAL CHARACTERIZATION OF INFRARED FLARE MATERIAL COMBUSTION WITH REMOTE HIGH-RESOLUTION FOURIER-TRANSFORM INFRARED SPECTROMETRY

The infrared emission characterization of high intensity IR flare mate rial combustion is studied using a remote sensing Fourier transform in frared spectrometer. The emission spectra have been recorded between 4 700 and 740 cm(-1) with a spectral resolution of 0.24 cm(-1). The spec tral radiance distribution of the IR flare material combustion has bee n given. A number of combustion products have been determined directly and quantitatively. The flame temperature can be estimated remotely a nd directly from the line intensity distributions of the fine structur es of the emission fundamental bands of gaseous molecules, such as HF, HCl, CO and/or H2O.
