摘要: Abstract We report on the observation of strong UV diffuse band around 380 nm in direct one photon excitation sodium molecule using 351 laser radiation from an excimer laser. The emission, though less intense by order magnitude comparison with violet bands, shows a clear spectral narrowing increasing temperature. In addition, we some interesting parametric dependences bands region 420–460 nm. results may help clarifying nature processes involved populating upper levels responsible for these emissions which have lately been conclusively identified.
