Abstract
IN the alkaline spectra, very long absorption series have been observed. Wood and Fortrat have detected 56 terms of the Na, 3S–nP series. One might expect that the high terms of the series would be destroyed by adding a foreign gas, as the excited states of high quantum number, have such a large volume that the number of molecules of the foreign gas contained in it can be, under experimental conditions, of the order of 10,000.
