Table 1
Calculated quantum yields of C(1D), C(1 S), O(1 D), and C(1 S)/C(1D) from solar photolysis of CO via photoionisation cross-sections of the C atom and the solar spectra from different sources.
| Quantum yields (%) | ||||
|---|---|---|---|---|
| C(1S) | C(1D) | O(1D) | C(1S)/C(1D) | |
| BR1(a)/S1(b) | 0.12–0.19 | 4.67–9.76 | 3.56–5.73 | 1.21–3.98 |
| BR1/S2(b) | 0.08–0.12 | 9.38–16.44 | 9.76–12.53 | 0.47–1.28 |
| BR2(a)/S1 | 0.15–0.23 | 5.50–11.33 | 3.40–5.44 | 1.31–4.24 |
| BR2/S2 | 0.10–0.15 | 10.31–17.92 | 9.65–12.35 | 0.54–1.46 |
Notes. (a) BR1 and BR2 are branching ratios normalised by using photoionisation cross-sections of the C atom from Burke & Taylor (1979); Cantu et al. (1981) and https://phidrates.space.swri.edu/, respectively. (b) S1 and S2 are solar photon flux from Huebner et al. (1992), and the solar spectrum (normalised intensity) from Del Zanna (2019), respectively.
