Abstract

The identification of suitable ro-vibronic excitation and fluorescence transitions of the NO molecule has been carried out as a pre-requisite to the application of two line thermometric (TLT) at the HEG. Excitation-fluorescence spectra were recorded using a tunable ArF eximer laser and a heated cell containing NO/N2 mixtures at differenttemperatures and pressures. Excitation lines of the different electronic transitions gamma, beta and epsilon, suitable for the determination of temperatures, could be identified. Moreover, fluorescence spectra of two selected NO transitions were considered. They exhibit considerable variation with temperature and pressure. From this investigation fluorescence lines for narrowband TLT application were nominated.
