The original version of this article unfortunately contained a typo in Table 2. In the column headings of Table 2, ΔG(p–p) should be changed to ΔG(t–t), also the table caption is modified. The corrected table is given below as:

Table 2 S0/S1 energy gaps {ΔG(t–t)} and the heats of reaction {ΔG(p–t)} from the common planar (B1u) state to each of the twisted structures in CH2Cl2 and MeOH solvents (and in vacuum); the dihedral angles ω 1ω 4 are defined with respect to the central four-membered ring in unit of degrees
