Fig. 6. (a) Absorption spectral changes of a CO2-saturated DMA solution containing Os (0.1 mM) and BI(OH)H (0.2 M) during irradiation at 480 nm with a light intensity of 2.6 × 10−8 einstein s−1 (0–42 min at 6 min intervals) and (b) difference spectra from post- and pre-irradiation spectra. The blue and red lines represent the spectra before irradiation and after irradiation for 42 min, respectively.
