CO2-broadening coefficients in the ν1 + ν2 and ν2 + ν3 bands of H2S

Key Points

• CO2-broadening coefficients impact the infrared absorption characteristics of H2S bands.
• Significant variations were noted in both the ν1 + ν2 and ν2 + ν3 bands under varying conditions.
• Spectroscopic measurements were used to assess the broadening effects in H2S due to CO2 interaction.
• Understanding these coefficients can improve atmospheric modeling and predictive accuracy for H2S emissions.
