The experimental quenching data for CCl2 in the excited state, A(1)B(1) (0,4,0), by alcohols were obtained through observing its time-resolved total fluorescence signal, which showed a superposition of two exponential decay components. The quenching rate constants K-A for CCl2 (A) State and K-a for CCl2 (a) state were derived by analyzing the experimental data according to a proposed three-level-model to deal with CCl2 (X(1)A(1),A(1)B(1),a(3)B(1)) system. K-A and K-a increase on the whole with increasing the number of C-H bonds in alcohol molecules.
