✦ Synopsis

A weak fluorescence was observed from benzophenone at 25650 cm+ with a quantum yield of ==lO-' at 5°K. With the assumption that * n,r* -3 n,r* intersystem crossing is more efficient than r n,~* + 3 n,~*, the temperature dependence of the quantum yield sets the 3n,n* level <, 50 cm-' above the 'n,~* level: 3E, rr = 26670 cm-' _

The vertical and adiabatic excitation energies between the ground and lowest two triplet states of acrolein were studied using ab initio correlated wavefunctions. A double zeta basis set was used in the configuration interaction calculations and each configuration expansion included about 6000 deter
