| 英文摘要 | Despite a seemingly simple appearance, cyclobutanetetraone (C4O4) has four low-lying electronic states. Determining the theoretically has been proven to be considerably challenging and remains energetic ordering of these states and the ground state of C4O4- largely unresolved to date. Here, we report a low-temperature negative ion photoelectron spectroscopic approach. Well-resolved spectra were obtained at both 193 and 266 nm. Combined with recent theoretical studies and our own Franck-Condon factors simulations, the ground state of C4O4- and the ground and two low-lying excited states of C4O4 are determined to be (2)A(2u), B-3(2u), (1)A(1g) (8 pi), and B-1(2u), respectively. The frequency of the ring breathing mode (1810 +/- 20 cm(-1)), the electron affinity (3.475 +/- 0.005 eV), and the term values of (1)A(1g) (8 pi) (6.27 +/- 0.5 kJ/mol) and B-1(2u) (13.50 +/- 0.5 kJ/mol) are also directly obtained from the experiments. |
