✦ Synopsis

With the aid of the crystullographic data, obtained anew, the Zeeman splitting pattern observed with the longest wavelength singlet-to-triplet absorp!ion of the acetophenone single crystal has been analyzed. The optically active spin state is T,,, which is mixed by spin-orbit interaction with u,rr* singlet excited states. This result is only consistent with the rr,~i* assignment for the lowest triplet state.

Ab initio calculations have been carried out for the T(3B,u) and V('BIu) states of ethylene in a planar nuclear conf@ration. A "double-zeta" gaussian basis, augmented by diffuse functions, was used. A wide variety of configuration interaction wavefunctions (including as many as 1605 configurations)
