Changes in absorption with and without nanorods.
(a) Changes in the absorption at the transition band R(30) (cold band 00001 → 00031) and band R(27e) (hot band 01101 → 01131) due to UV irradiation (λ = 213 nm) of CO2. Bold lines were obtained for irradiation of the nanorods and dotted lines were obtained for irradiation without nanorods. (b) Changes in the absorption of the R branch for the 00001 → 00031 transition band due to UV irradiation, with (at time t = 10000 s) and without using nanorods (at time t = 1840 s). (c) Changes in the absorption of the P branch for the 00001 → 00031 transition band due to UV irradiation, with (at time t = 10000 sec) and without nanorods (at time t = 1840 s). (d) Changes in the absorption of hot transition band 01101 → 01131 due to UV irradiation, with (at time t = 10000 s) and without nanorods (at time t = 1840 s).
