Abstract
An absorption band in gaseous ammonia at 3 μ is observed at high resolution and attributed to the doubly degenerate fundamental ν3. The constants ν0 = 3442.9, A0 = A1 = 6.13, A1ζ = 0.29, and B1 = 9.75 cm.−1 describe the band. Many of the observed lines are doublets. This doubling is a result of the inversion of the ammonia molecule and the value 1.1 cm.−1 is calculated for the inversion doubling of the 0010 state.Keywords
