a Schematics of the linear combination of the strongly coupled lowest-energy acoustic phonon eigendisplacements of A1 symmetry at all q = M points, see Supplementary Fig. 3. b Phonon spectral function of MoS2 at 800 K, with the adiabatic phonon band structure denoted with dashed black line. c Eliashberg spectral function in the adiabatic (A, red) and nonadiabatic (NA, blue) approximations together with the corresponding EPC cumulative constant λ(ω). d EPC strength λ and logarithmic average frequency \({\omega }_{\log }\) computed with NA phonons. e Superconducting Tc calculated using McMillan’s (MM) formula (hollow red circles), the Allen–Dynes (AD) formula (full red dots), and the isotropic Migdal–Eliashberg (ME) formalism (golden stars). Cross symbols denote the calculations which include spin–orbit coupling.
