A spectrophone and a CO2 laser source were used to determine the absorption coefficients of NH3 at seventy-seven laser lines in the 00°1–02°0 band at 9.4 μm and the 00°1–10°0 band at 10.4 μm. The NH3 was buffered with N2 to 1 atm at 295 K; its concentration ranged from 30 ppm to 200 ppm. The absorption coefficients and their probable errors are tabulated.
