We report the negative ion photoelectron spectroscopy of the hydroxymethoxide anion, H2C(OH)O-. The photoelectron spectra show that 3.49 eV photodetachment produces two distinct electronic states of the neutral hydroxymethoxy radical (H2C(OH)O⋅). The H2C(OH)O⋅ ground state (X̃ 2A) photoelectron spectrum exhibits a vibrational progression consisting primarily of the OCO symmetric and asymmetric s...
We report an angle resolved photoemission spectroscopy study of quantum critical scaling in the single-particle spectral function of a novel anisotropic metal Li_{0.9}Mo_{6}O_{17}. We find a temperature (T) scaling exponent value and also low-T angle resolved photoemission spectroscopy line shapes that are very challenging for current one-dimensional theory frameworks. These results add a new s...
The 351.1-nm (3.532-eV) photoelectron spectrum of the nitrite anion (NO,) is reported. The electron affinity of NO2 is found to be 2.273 f 0.005 eV, which leads to the heat of formation AfHoo(NOJ = -183.4 f 0.9 k.J/fiol(-43.8 * 0.2 kcal/mol). Vibrational progressions of the symmetric stretch and bending modes of nitrogen dioxide, N02(X2AI), are observed up to 8000 cm-’ above the ground state. O...
