- While Renner's theoretical study concerned the linear triatomic molecule CO 2, the first actual observation of the Renner Teller effect was in the electronic absorption spectrum of NH 2 and its isotopologue ND 2 . [ 4 ] In 1959 Dressler and Ramsay found that the first electronically excited states of these triatomic molecules have a linear geometry and they observed in these excited states an unusual type of vibronic structure : the Renner Teller effect.
