Abstract: Continuous wave excitation and wavelength-resolved fluorescence techniques have been used to study the self-quenching and energy transfer kinetics of $Br_{2} (B)$. A self-quenching rate of $4\times 10^{-10} cm^{3} molecule^{-1} s^{-1}$ was observed for the levels with $v>10, J^{\prime}>15$, in excellent agreement with the results from pulsed $measurements.^{1}$ The rate constants for rotational energy transfer (summed over all final states) were found to be around $6\times 10^{-11} cm^{3} molecule^{-1} S^{-1}$. An upper bound of $5\times 10^{-12} cm^{3} molecule^{-1} S^{-1}$ was established for the vibrational energy transfer rate constant. The c.w. measurements are at variance with the energy transfer rate constants obtained from models of the time-resolved fluorescence decay kinetics.1 The reason for these discrepancies will be discussed.
