Diode laser probing has been used to follow the time dependent changes in the populations of low lying vibrational states of CO2 produced via quenching of Hg(6 3P1) initially excited by a pulse from a doubled dye laser. The conversion of mercury electronic energy into CO2 vibrational energy is quite efficient and mode specific. The ratio of the number of bending mode quanta to the number of asymmetric stretch quanta produced by the quenching process is 40±12. The rate of filling of both the bending and asymmetric stretch levels is identical and corresponds to 80 CO2/CO2 gas kinetic collisions. This data, taken in conjunction with the known quenching rate of Hg(6 3P1) by CO2 (four gas kinetic collisions) suggests that the quenching process produces a metastable state of CO2 which is either a bent electronic triplet or a highly excited vibrational level of the ground electronic state.
