Abstract

A tunable diode laser spectrometer has been used to determine pressure broadening coefficients due to collision with the foreign gases air, H₂, O₂ and N₂ in the ν₄ and ν₆ bands of H₂CO between 9 and 11 μm. Absolute line strengths for twenty-eight transitions have also been determined. The broadening coefficients are very similar to theoretical literature values in the cases of air, N₂, and O₂. The H₂–H₂CO values are in good agreement with earlier experimental millimeter wave results.
