Schwartz-Lavi, I. Bar, and S. Rosenwaks* Department of Physics, Ben-Gurion University of the Negev, Beer-Sheva 841 05, Israel (Received: February 2, 1987) The rotational alignment, A-doubling, and spin-orbit populations of the NO fragment following the photodissociation of (CH3)*NN0 and (CH3)+20N0 in different absorption bands are determined. The results for the S,(nr*) - So and S2(rr*) - So transitions in both molecules indicate planarity of the fragmentation processes and an A“ symmetry of the S, state. For the S2(rr*) - So transition in (CH3),NN0 the results imply an A' symmetry of the S2 state …
