✦ Synopsis

The use for the first time of a hgh-resolution Fourier transform spectrometer to analyse the laser-induced fluorescence from a ring dye laser allows observation of vibrational levels of the 'Liz molecule close to the ground-state dissociation limit. This extends the known potential curve from 5.18 -9 (88% of the dissociation energy De) to 8.5 1 A (99.75 of De)_ Long-range par.tmetersareDe = 8516.9 f 0.5 cm-'. Ch = (2.4 + 0.5) X IO6 A6 cm-' . VD = 40.3 f 0.3. From single or double resonance excitation the technique will allou the precise observation of the full potential curve of a number of electronic states.
