Long-range electron binding to quadrupolar molecules.
An excess electron can be bound to a molecule in a very diffuse orbital as a result of the long-range contributions of the molecular electrostatic field. Following a systematic search, we report experimental evidence that quadrupole binding occurs for the trans-succinonitrile molecule (EA=20+/-2 meV), while the gauche-succinonitrile conformer supports a dipole-bound anion state (EA=108+/-10 meV...
متن کاملFinite-size scaling for critical conditions for stable quadrupole-bound anions.
We present finite-size scaling calculations of the critical parameters for binding an electron to a finite linear quadrupole field. This approach gives very accurate results for the critical parameters by using a systematic expansion in a finite basis set. The model Hamiltonian consists of a charge Q located at the origin of the coordinates and k charges -Q/k located at distances R(i), i=1, em ...
متن کاملMultipole-Bound Anions and Photodetachment Spectroscopy
Photoelectron spectra of MgO n n 1 5 reveal a surprising trend: The electron binding energy decreases from n 1 to 4, and then increases from 4 to 5. Ab initio calculations suggest this pattern is related to the electrostatic interaction between the extra electron and the charge distribution of the neutral cluster. This interaction is significant in MgO and MgO 2 5 , for which the lowest nonvani...
متن کاملStudy of halogen – carbon dioxide clusters and the fluoroformyloxyl radical by photodetachment of X 2 ( CO 2 ) ( X 5 I , Cl , Br ) and FCO 2 2
Photoelectron spectra have been measured for the anions X~CO2!, with X5I, Br, Cl, and F. The vibrationally resolved spectra show that I~CO2!, Br ~CO2!, and Cl ~CO2! are primarily electrostatically bound clusters, although the charge-quadrupole interaction is strong enough to distort the CO2 molecule by as much as 10° @in Cl ~CO2!#. Ab initio calculations and electrostatic models are used to des...
متن کاملInfrared spectroscopy of mass-selected neutral molecular systems without chromophore: the formamide monomer and dimer
The paper presents IR spectroscopic data and theoretical frequency calculations, in the C–H and N–H stretch region, on jet-cooled formamide molecules and dimers. By using dipolebound or quadrupole-bound anion formation, one is able to monitor IR absorption in the neutral beam on mass-selected species. For isolated formamide, resonant IR excitation leads to autodetachment of the excess electron ...
