✦ Synopsis

The nitrogen and oxygen broadening coefficients of ozone have been experimentally obtained at two low temperatures (227 and 186 K) in the n 1 / n 3 band, located at 2110 cm 01 . Thirty-five transitions have been chosen to derive the n coefficient defined by a(T ) Å a(T o )r(T o /T ) n . This is found, for both N 2 and O 2 , to be n Å 0.72 { 0.08, where 0.08 is two standard deviations. This value is accurate enough for atmospheric applications.
