Nitridation on a Ti(0001)-1$$times$$1 surface using a supersonic N$$_{2}$$ molecular beam was investigated by real-time photoelectron spectroscopy to clarify the adsorption reaction dynamics of N$$_{2}$$ molecule on the Ti surface. In a whole N$$_{2}$$ dosage region examined, N 1s spectra can be fitted well with two chemically-shifted components, the binding energies of which are 396.9 and 396.6 eV, respectively. For both the components, the initial sticking probability S$$_{0}$$ shows a decrease with increasing incident energy in the overall trend, while has significant minima at 0.3 and 1.5 eV. Such incident energy dependences of S$$_{0}$$ suggest that the chemisorbed states are similarly caused by a trapping-mediated adsorption process through a physisorption state at lower incident energy than 0.3 eV and an activated adsorption process becomes dominant at higher incident energy than 0.3 eV.
