| Abstract: | The processes responsible for the emission of Na-D line in the Earth's atmosphere and laboratory are briefly reviewed. From the laboratory results of Ghoshet al. (1970), the rate coefficient of reactions exciting sodium D line is estimated to be 4.73×10–25 cm6/sec2, and its intensity in the nightglow is found to be about 114R in summer and 302R in winter. |
