✦ Synopsis

The feasibility of determining nuclear quadrupole hyperfine splittings in the ground electronic state of a polyatomic molecule using a double resonance quantum beat method has been demonstrated. Pyrimidine molecules were coherently excited into single rotational states of the So 201 ( 13a ~) vibrational level. The resulting hyperfine level coherences were then probed, after a variable time delay, by excitation to the $1 0 ° level with subsequent fluorescence detection. Analysis showed that the quadrupole structure in the 20 ~ (13a l) level is similar to that previously measured in the vibrational ground state. Applications of this method and possible experimental extensions are discussed.

By introducing the IR-UV pump-probe technique to detect molecular quantum beats, this phenomenon is utilized as a Doppler-free time domain spectroscopy for the electronic ground state. The technique is demonstrated with Stark quantum beats of vibrationally excited So levels to determine the electric
