Vibrationally resolved photofragment spectroscopy of FeO
نویسندگان
چکیده
We report the first vibrationally resolved spectroscopic study of FeO. We observe the 0←0 and 1←0 bands of a S←X S transition at 28 648.7 and 29 311 cm. Under slightly modified source conditions the 1←1 transition is observed at 28 473 cm. In addition to establishing an upper limit D0 (Fe1–O!<342.7 kJ/mol, our results give the first experimental measurements of the vibrational frequencies in both the ground state, n09583864 cm , and the excited electronic state, n085662 62 cm. Partially resolved rotational structure underlying the vibrational peaks has been analyzed to measure the predissociation lifetime and estimate the change in molecular constants upon electronic excitation. © 1999 American Institute of Physics. @S0021-9606~99!00328-1#

Electronic spectra of gas-phase V+(OCO) are measured in the near-infrared from 6050 to 7420 cm(-1) and in the visible from 15,500 to 16,560 cm(-1), using photofragment spectroscopy. The near-IR band is complex, with a 107 cm(-1) progression in the metal-ligand stretch. The visible band shows clearly resolved vibrational progressions in the metal-ligand stretch and rock, and in the OCO bend, as ...
متن کاملOvertone spectroscopy of H2O clusters in the V(OH) = 2 manifold: infrared-ultraviolet vibrationally mediated dissociation studies.
Spectroscopy and predissociation dynamics of (H2O)2 and Ar-H2O are investigated with vibrationally mediated dissociation (VMD) techniques, wherein upsilon(OH) = 2 overtones of the complexes are selectively prepared with direct infrared pumping, followed by 193 nm photolysis of the excited H2O molecules. As a function of relative laser timing, the photolysis breaks H2O into OH and H fragments ei...
