The Far Ultraviolet Absorption Spectrum of N2O

Abstract

The absorption spectrum of nitrous oxide below 2200A has been reinvestigated. Much new material has been found, particularly below 1550A, including some discrete systems of bands, and some continuous regions of absorption. No bands are found below 997A, but only continous absorption down to about 850A, the limit of observation. A Rydberg series was found, converging to an ionization potential of 12.66 volts. Evidence was found for a total of ten electronic states including the members of the Rydberg series. The vibration frequency in the electronic transition around 1500A is 621 cm^—1.
