Laser induced fluorescence spectra of the a 3Πu–X 1Σ+g band of Na2 by molecular beam

Laser induced fluorescence spectra of the a 3Πu–X 1Σ+g band of Na2 are studied using the crossed molecular beam and laser technique in the wavelength region 14 700–16 000 cm−1. All band origins of a 3Πu0–X 1Σ+g, v″=0 transitions in this wavelength region are observed. Their wavelengths are tabulated and analyzed.
