Comments: The absorption spectrum of nitrous oxide (N2O) 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.
