Collisional radiative models for atomic hydrogen and molecular hydrogen are conveniently used to study the boundary plasmas of magnetic confined fusion plasmas. These models help us to analyze the observed emission intensities and provide effective rate coefficients that are indispensable to neutral particle simulations. This paper will review these models and some of results obtained using these models. It will be pointed out that the effective reaction rate coefficients starting from molecules and molecular ions strongly depend on their initial vibrational levels.
