Optical–optical double resonance (OODR) spectroscopy has been applied to the rotational and vibronic analysis of the thirty nine eigenstates of NO2 existing in the energy region of 16,980–17,124 cm-1 above the ground state. These excited states are concluded to be the mixed states of NO2 generated by spin-orbit and/or orbital-rotation interaction between the B2 and A1 vibronic levels. The mixing mechanism of the excited states is discussed in terms of available information on the visible excited states of NO2.
