Abstract: In recent years, combined experimental and theoretical efforts have brought valuable information on the kinetics of reactive collisions between molecular hydrogen and an electronically excited atom X (where X = C (D-1) , N (D-2) , O (D-1) or S (D-1)). These four reactions have been comparatively studied together in numerous occasions in the past due to the similar importance of complex-forming mechanisms found in their overall dynamics. In this work, we compile the most updated information on these investigations making a special emphasis from the theoretical side on statistically based techniques, in an attempt to test the possible insertion nature of the overall dynamics. Besides a description of the experimental details of the kinetics investigation, a comparison of the measured rate constants over a temperature range between 50 and 300 K with the most recent theoretical calculations is presented.
