Abstract

Thallium monofluoride (TlF) is a prime candidate molecule for precision measurements aimed at discovering new physics. Optical cycling on the B \leftarrow X transition around 271 nm enhances this potential. Hyperfine resolved ultraviolet spectra have been reported to determine the degree of rotational level mixing in the B-state and the efficiency of laser cooling on the B \leftarrow X transition [E. B. Norrgard et al.{\it et~al.}, Physical Review A 95{\bf 95}, 062506 (2017)]. Using these high-resolution spectra, the hyperfine structure in the B-state of TlF is re-analysed and the magnitude of the Λ\Lambda-doubling in the B-state is discussed.
