Stark Spectroscopy of NH3 ν2 Band by 10-μ CO2 and N2O Lasers

Abstract

The Stark spectrum of the ${\nu }_2$ band of ¹⁴NH₃ is studied using CO₂ and N₂O lasers equipped with a grating for the laser line selection. About 100 coincidences between NH₃ lines of $\text{J≤7}$ and the laser lines are obtained. The NH₃ line positions relative to the laser lines are calculated using the data for the dipole moment obtained by the same experiment.
