First detection and analysis of the 3ν1+3ν2+ν3 band of NO2 near 7587 cm−1.
414 lines were assigned with rotational quantum numbers N and Ka up to 32 and 6.
Effective Hamiltonian modeling.
Coriolis resonance coupling with three dark states: (350), (062) and (312).
The 3ν1+3ν2+ν3 band is the weakest NO2 band rovibrationnally assigned so far.
