Quenching of Fluorescence in I2

Problem 7.14, Chemical Kinetics and Reaction Dynamics[1]:
Consider the quenching of fluorescence in I2. The fluorescence intensity, If , from the excited level (ν=25, J=34) is measured as a function of helium concentration relative to its value, If0 in the absence of helium. From equation 7.21 [1], we note that at zero quencher pressure, so that , where kq corresponds to the sum of all processes leading to the depopulation of the initially excited level. A table of results is given below. Determine kq given that kf is 1.4×106 s−1.
