文摘

The electron spectrum of the tungsten monooxide molecule is observed in the 550–800 nm region using intracavity laser absorption spectroscopy. The WO molecules are produced in a pulsed electric discharge through the mixture of tungsten hexacarbonyl vapors. The spectrum is recorded using a diffraction spectrometer (resolving power of 240000). The bands in the 16400–15500 cm–1 region are assigned to the 3Π₀–X3Σ+ component of the 3Π₀–X3Σ+–^{3XΣ+ electron transition. The rotational analysis of the 0-0 and 1-0 bands is carried out and the rotational constants for the ground X″3Σ and the exited 3Π₀ states are computed: В′ = 0.385738 cm–1, B″ = 0.415538 cm–1.}
