Extended Data Table 2 Results from the photochemical experiment

From: Synthesis of 13C-depleted organic matter from CO in a reducing early Martian atmosphere

  1. Results from the photochemical experiment. Initially, a 1:2:8 mixture of CO, O2, and N2 was photolyzed using the same UV source as in the experiments shown in Table 1. δ13C denotes the carbon isotopic composition of CO normalized against the VPDB.
