## The time dependence of CO lowast J is

The kinetic model for the dependence of CO2∗(J) for early times included two types of collisional energy-loss NSC697923 for CsH(v), namely, (1) quenching by CO2 and (2) H2. The influences of the relaxation pathways were observed in the transient behavior of CO2 [right-hand side, Eq. (19)]. Given kv,tot as the total quenching rate constant for CsH(v) and [M] as the total concentration of CO2 and H2, kv,q1[CO2]+kv,q2[H2]=[αkv,q1+(1-α)kv,q2][M]=kv,tot[M]kv,q1[CO2]+kv,q2[H2]=[αkv,q1+(1-α)kv,q2][M]=kv,tot[M] ( Fig. 6). The natural logarithm of the left-hand side of Eq. (22) was plotted as a function of time ( Fig. 16); the slope of the best-fit line was kv,totkv,tot [M]. Table 7 lists the values of kv,totkv,tot obtained using the data for CO2(0000) [J = 36–60] and CO2(0001) [J = 5–31]. The rate constants derived from the appearance of the CO2(0000) state [J = 36–60] were found to be kv=16,tot=1.31×10-11kv=16,tot=1.31×10-11, kv=22,tot=6.1×10-11kv=22,tot=6.1×10-11, and kv=23,tot=3.9×10-11cm3molecule-1s-1 for J = 36; chlorophyll a for J = 36 were kv=16,tot=2.70×10-11kv=16,tot=2.70×10-11, kv=22,tot=11.9×10-11kv=22,tot=11.9×10-11, and kv=23,tot=7.9×10-11cm3molecule-1s-1. The rate constants monotonically increased for the higher-order states. kv,totkv,tot values remained constant for the (0001) state [J = 5–31].
