Following our previous work [Y.-H. Ho, Y.-H. Wang, H.-Y. Chen, Physical Review B, 89, 155316, 2014], we systematically calculate the magneto-optical properties of various transition metal dichalcogenides monolayer. The intrinsic spin-orbit coupling gives rise to the spin-split electronic states, while a perpendicular magnetic field further induces a valley splitting. In magneto-optical spectra with linearly polarized light, spectral features are spin and valley-polarized. Compounds are different from one another in terms of transition energies and appearance of twin peaks. Our numerical results can serve as a guide for future experimental identification.
