We investigate the contributions of the lowest two (1)A '' states in the UV photodissociation of N2O employing three-dimensional potential energy surfaces and transition dipole moment functions. Because the transition dipole moments are much smaller than for the 2(1)A' state, we conclude that excitation of the (1)A ''. states has a marginal effect The dense vibrational spectrum of the quasi-bound 2(1)A '' state possibly explains some of the tiny, noise like structures of the measured absorption spectrum.
