OH-Laser Induced Fluorescence (OH-LIF) spectrum induced by P_2 (7) line of transition A^2Σ^+-X^2Π(1-0) was investigated by use of the transition rate equations. The analysis results were applied to OH relative concentration measurement in a hydrogen diffusion flame. The results obtained are described as follows. (1) The computed OH-LIF spectrum by the transition rate equations agrees with the experimental result well. (2) It was clarified that the ratio of the OH-LIF spectrum intensity by the vibrational transition (1-1) and (0-0) to that by the transition (1-0) is a function of temperature and H_2O concentration. (3) The measured temperature and H_2O concentration profiles by the OH-LIF spectrum intensity ratio agree well with the numerical results. (4) The measured profiles of collisional quenching rate and OH relative concentration by the OH-LIF spectrum intensity ratio agree well with the numerical results.
