Integrated intensities of the infrared and QMS features of OCS for different flux conditions: CO:H₂S = 1:1, 5:1, 10:1, and 20:1. The infrared value is derived from the area of the ν₁ mode of OCS, while the QMS counterpart is calculated from the integrated desorption band for m/z = 60 peaking at ~89 K. The resulting yields are normalized to that of experiment 1 (CO:H₂S = 1:1). The upper x-axis shows the corresponding ratios of H/CO, signaling the decrease in H-atom availability with increasing CO fractions.
