We demonstrate Stark effect measurements at room temperature of high-lying Rydberg states in nitric oxide. These states are generated using a three-photon continuous-wave excitation scheme. The readout is based on the detection of charged particles created by collisional ionization of Rydberg molecules. A theoretical discussion of the obtained experimental results is given.

Keywords: Stark effect; nitric oxide; trace-gas sensor; Rydberg state; Electrical detection
