The absorption spectrum of nitrous oxide (N 2 O) has been determined at five temperatures from 194 to 302 K and over the wavelength range 173‐240 nm. The absorption cross sections as a function of wavelength and temperature are expressed by a nine‐term polynomial in a form useful for atmospheric models. The high resolution structure between 173 and 190 nm has been observed more clearly than by previous studies.
