Well-known as an important intermediate in atmospheric chemistry, the nitrate radical (NO_3) has been extensively studied both experimentally and theoretically. The three energetically lowest electronic states (tilde{X} ^{2}A_{2}^', tilde{A} ^{2}E^'', and tilde{B} ^{2}E^') are strongly coupled by vibronic interactions and hence it is a textbook molecule for understanding the coupling between nearby potential energy surfaces. Such coupling has been treated in considerable detail theoretically. However, corresponding experimental characterization of the interaction is much less detailed. The experimental results primarily consist of IR measurements of vibrational transitions in the ground state. In addition, the electronically forbidden tilde{A}-tilde{X} transition has been observed in ambient temperature CRDS studies. To understand both the Jahn-Teller and pseudo Jahn-Teller coupling in the molecule, further measurements are required with different selection rules and/or higher resolution to resolve the rotational structures of different transitions. In our group, a high-resolution (source Δν≈ 100 MHz in NIR region), jet-cooled CRDS system can be applied to rotationally resolve the electronically forbidden tilde{A}-tilde{X} transition. Furthermore, our high-resolution LIF/SEP system (source Δν≈ 100 MHz) can provide the direct, rotationally resolved measurements of the tilde{B}-tilde{X} and tilde{B}-tilde{A} transitions by operating in the LIF and SEP modes respectively. Such data can provide unambiguous spectral assignments in the tilde{X}, tilde{A} and tilde{B} states.
