Crynodeb

The application of concentration-modulated absorption spectroscopy, COMAS, to the determination of lifetimes of the electronic states of absorbing species is discussed. The theory behind the lifetime calculations is described and experimental results for lithium in a hydrocarbon flame are reported. The lifetime of the 2p2P 3 2, 1 2 and 3d2D 5 2, 3 2 states are respectively measured as 528±20 and 216±20 ps for lithium atoms in an ethyne-air flame. The power of the technique in measuring accurately the lifetimes of high-lying thermally excited state species is discussed and areas for further work are suggested.
