Abstract: | We report an investigation of the resonance fluorescence spectrum of NO2 excited by several laser lines. Sixty transitions, mostly in ν2 progressions of the ground state, have been assigned. Analysis of the spectra extend the knowledge of the ground state constants, especially of the anharmonic coefficients. It is possible to establish that transitions are occurring to a 2B1 state and to a 2B2 state in the same energy region. |
