Experimentally and theoretically determined magnetic and electric dipole moments, bond distances, and vibrational spacings are used for a comparative study of the bonding in ThF and ThCl. Numerous bands in the visible electronic spectra between 16 400 and 18 800 cm -1 of supersonically cooled molecular beam samples have been detected using medium-resolution (0.1 cm -1 ) 2D spectroscopy. High-resolution (δ 1/2< 20 MHz) field-free, Stark, and Zeeman spectroscopy of the detected [18.6]ω = 3/2 - X 2 δ 3/2 band of ThF near 538.4 nm and the [18.2]ω = 3/2 - X 2 δ 3/2 band of ThCl near 551.0 nm have been recorded and analyzed. Stark shifts and splitting were analyzed to produce |μ→ el
