The permanent electric dipole moments of chromium and vanadium mononitride: CrN and VN
- Department of Chemistry and Biochemistry, Arizona State University, Tempe, Arizona 85287-1604 (United States)
The P{sub e}(1), F{sup {double_prime}}=2.5 branch feature of the (0,0) Dthinsp{sup 3}{Pi}{sub 0e}{endash}Xthinsp{sup 3}{Delta}{sub 1} band system of {sup 51}VN was recorded as a function of an applied static electric field. The resultant Stark splitting and shifts were analyzed giving values of 3.07(7) D and 6.1(4) D for the Xthinsp{sup 3}{Delta}{sub 1} and Dthinsp{sup 3}{Pi}{sub 0e} states, respectively, for the magnitude of the permanent electric dipole moment, {vert_bar}{mu}{vert_bar}. Similarly, the R{sub ee}(0.5) branch feature of the (0,0) Athinsp{sup 4}{Pi}{sub 3/2}{endash}Xthinsp{sup 4}{Sigma}{sup {minus}} band system of {sup 52}CrN was recorded as a function of an applied static electric field and analyzed to produce {vert_bar}{mu}{vert_bar} values of 2.31(4) D and 5.42(2) D for the Xthinsp{sup 4}{Sigma}{sup {minus}} and Athinsp{sup 4}{Pi}{sub 3/2} states, respectively. In order to facilitate the dipole moment determinations for {sup 52}CrN it was necessary to record and analyze the field free spectrum of the (0,0) Athinsp{sup 4}{Pi}{sub 3/2}{endash}Xthinsp{sup 4}{Sigma}{sup {minus}} subband system. A comparison of the dipole moments for the first row monoxides and mononitrides is made and trends are discussed with reference to a molecular orbital correlation scheme. {copyright} {ital 1999 American Institute of Physics.}
