摘要：

Laser induced fluorescence spectra of the A1Σu+ → X1Σg+ system have been recorded by Fourier transform spectrometry. The ground electronic state of the 39K2 molecule is characterized up to v = 75, encompassing 99.3% of the potential depth. A long-range study of the potential energy curve gave the coefficients of the multipolar expansion and the dissociation energy is found to be De = 4451 ± 1.5 cm-1 (0.5519 ± 0.0002 eV). © 1991.
