Top panel shows the JWST spectrum of COCONUTS-2 b in the filter G395H with horizontal lines indicating the molecular features which are recognizable in the spectrum. We also included the uncertainty in the flux in light gray. Bottom panel shows the opacities for each identified molecule which we obtained from the DACE database (R. J. Barber et al. 2006; L. S. Rothman et al. 2010; S. N. Yurchenko et al. 2011; A. A. A. Azzam et al. 2016; R. J. Hargreaves et al. 2020; S. L. Grimm et al. 2021; J. Tennyson et al. 2024).
