✦ Synopsis
The high-resolution emission spectrum of molecular nitrogen was photographed in the vacuum ultraviolet from 82.6 to 124.2 nm. The use of a low-pressure Penning-type electric discharge source has led to considerably reduced selfabsorption at short wavelengths, making it possible to record as many as 283 emission bands. All emission bands have been rotationally analyzed, 215 being observed for the first time, and are reported in a separate publication. Energy values were deduced for the nonpredissociative or only slightly predissociative rovibronic levels in 10 singlet electronic excited states.
