Hyperfine Structure of the $B^3{\Pi }_1$ State and Predictions of Optical Cycling Behavior in the $X\to B$ transition of TlF

Eric B. Norrgard, Eustace R. Edwards, Daniel J. McCarron +6

The rotational and hyperfine spectrum of the $X^1{\Sigma }^{+}\to B^3{\Pi }_1$ transition in TlF molecules was measured using laser-induced fluorescence from both a thermal and a cryogen…
