Synthetic H₂ spectrum produced with a shock model with velocity 30 km s⁻¹, preshock density 10⁴ cm⁻³, a transverse magnetic field strength of 10 µG, and no external UV radiation. Wavelength ranges of the NIRSpec and MIRI spectrographs, as well as the wide-, medium-, and narrow-band filters for NIRCam and the MIRI filters on JWST are indicated as black and gray horizontal bars. The colors are for lines with different vibrational upper levels. The resolving power is assumed to be uniform across the wavelength range at λ/Δλ = 2500.
