Abstract:
A number of low-rotational lines of the A (2)Sigma(-) <-- X (2)Pi(3/2)(0,0) subband of a molecular beam of copper monoxide, CuO, were recorded field free and in the presence of a static electric field. A set of optimized fine and hyperfine parameters for the A (2)Sigma(-)(upsilon(') = 0) state was produced from the analysis of the field-free spectrum. The permanent electric dipole moments mu for the A (2)Sigma(-)(upsilon = 0) and X (2)Pi(3/2)(upsilon = 0) states were determined to be 1.12(71) and 4.57(3) D, respectively, from the analysis of the observed Stark shifts. The error of the experimentally determined mu value for the X (2)Pi(3/2)(upsilon = 0) state is approximately ten times less than that for the previously determined value: mu = 4.45(30) D [T. C. Steimle et al., J. Chem. Phys. 87, 5670 (1987)]. The experimental mu values are compared with theoretical predictions.

Theoretically, studying electric dipoles leads to understanding why the resultant electric forces around us are weak. Since electric forces are strong, remnant net charges are rare. Hence, the interaction between dipoles helps us understand electrical interactions in...

When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
