IR_window_anesthetics

The net upward atmospheric radiance spectrum at the tropopause.22 Dashed lines are Planck functions for blackbody emissions at 290, 260, and 220 K, respectively. (B) IR absorption bands for CFC-11 (CCl3F), isoflurane, and sevoflurane. Halogenated organic compounds absorb strongly in ‘the atmospheric window’ region.
