摘要：

The 3 (1)Pi and 6 (1)Sigma(+) states of the NaK molecule were investigated by polarization labeling spectroscopy in a heat pipe oven. About 2000 molecular transitions in the 3 (1)Pi <-- X (1)Sigma(+) and 6 (1)Sigma(+) <-- X (1)Sigma(+) band systems were measured in the 24 600-27 700 cm(-1) spectral range. The analysis provided molecular constants and the potential-energy curve corresponding to 97% of the potential well of the 3 (1)Pi state. For the double minimum 6 (1)Sigma(+) state nearly the whole inner potential well was characterized. The results are compared with the predictions of recent theoretical calculations.
