Benzene singlet Rydberg states

Table 4 The Singlet Rydberg States of Benzene Comparison of SCVB Results with Other Theoretical Calculations and Experiment...

The results of these calculations show that the excited states of benzene fall into three classes covalent, ionic, and Rydberg. An example of a covalent state is the first singlet excited state, B2 , lying at an energy of 4.90 eV above the ground state. It may be represented to an excellent approximation simply as ... 

M. S. Child The first part of the talk by Prof. Neusser concerned intramolecular interaction between the Si and Ti states of benzene, and the second part referred to the high Rydberg spectrum. Each member of this singlet series must have a corresponding triplet, such that...
