Extended Data Fig. 3 | Systematic shifts of the Zeeman component 19+ of the
rotational hyperfine transition line 19. a, The trap’s amplitude is decreased
by 2.5 V from VRF(1) to VRF(2). The FWHM linewidth is 4 Hz, corresponding to 3 × 10−1 2
fractional FWHM. b, The light shift induced by the 266 nm and 1.4 μm
dissociation lasers, determined by comparing two spectroscopy modes.
‘Continuous’ indicates that the lasers are on when the terahertz radiation is
applied. ‘Interleaved’ indicates that the lasers and terahertz radiation are on
alternatingly.
