Statistical-band-model analysis and integrated intensity for the 21.8 micrometer bands of HNO3 vapor

The 21.8 μm absorption bands of HNO3 vapor were measured at 40°C. Statistical-band-model analysis of the data resulted in spectral-band-model parameters and yielded an integrated intensity of 393 ± 15% (cm−2 atm−1) at 40°C between 390 and 502 cm−1.
