Pseudo-continuous resonance enhanced multiphoton ionisation: application to the determination of the hyperfine constants of 208Pb19F

A highly efficient pseudo continuous resonance enhanced multiphoton ionisation detection scheme is presented that combines the sensitivity of resonance enhanced multiphoton ionisation (REMPI) with high resolution. This detection scheme is employed to obtain the A(v′ = 1) ← X 1(v = 0) spectra of 208Pb19F with a resolution of 90 MHz. The observed 19F hyperfine splittings are analysed in terms of effective hyperfine parameters that describe the interaction between the fluorine nuclear spin and that of the unpaired electron in the A and X 1 states of the molecule.

Precision spectroscopy of the {sup 207}Pb{sup 19}F molecule: Implications for measurement of P-odd and T-odd effects

Here we report precision microwave spectroscopy of pure rotational transitions of the {sup 207}Pb{sup 19}F isotopologue. We use these data to make predictions of the sensitivity of the molecule to P-odd, T-even and P-odd, T-odd effects.
