Determination of Electric Dipole Moments of NO₂²B₂ State By Stark Modulation Spectroscopy

Stark Modulation spectroscopic method was used to measure the A²B₂←X²A transition band near 593nm. The electric dipole monents of A²B₂ excited state could be obtained from analysis of the spectral intensity. While for accidentally degenerate levels, computer simulation of the spectral line shape was applied for determination of the dipole moments.
