The rotational alignment, Λ-doubling, and spin-orbit populations of the NO fragment following the photodissociation of (CH3)2NNO and (CH3)3CONO in different absorption bands are determined. The results for the S1(nπ*) ← S0 and S2(ππ*) ← S0 transitions in both molecules indicate planarity of the fragmentation processes and an A″ symmetry of the S1 state. For the S2(ππ*) ← S0 transition in (CH3)2NNO the results imply an A′ symmetry of the S2 state. The values obtained for the alignment are indicative of the difference between the directions of the transition dipole moment for the S1(nπ*) ← S0 and the S2(ππ*) ← S0 transitions.
