|Title:||Temperature dependence of electric field-gradient induced birefringence (Buckingham effect) and molecular quadrupole moment of N₂.: Comparison of experiment and theory||Contributor(s):||Ritchie, Geoffrey (author); Watson, Jonathan (author); Keir, Roland (author)||Publication Date:||2003||DOI:||10.1016/S0009-2614(03)00137-4||Handle Link:||https://hdl.handle.net/1959.11/1649||Abstract:||Observations of electric field-gradient induced birefringence (the Buckingham effect) in gaseous N₂ over a range of temperature (≈293–412 K) and pressure (up to ≈2000 kPa) are reported. Analysis of the data shows that the temperature-independent contribution to the effect is not negligible, and values of the molecular hyperpolarizability, B, and quadrupole moment, ⊖, are derived. In the case of the quadrupole moment, the experimental value [⊖=(−4.97±0.16)×10⁻⁴⁰ Cm²] and a state-of-the-art ab initio value [⊖=(−4.93±0.03)×10⁻⁴⁰ Cm²] due to Halkier, Coriani and Jørgensen [Chem. Phys. Lett. 294 (1998) 292] are in excellent agreement.||Publication Type:||Journal Article||Source of Publication:||Chemical Physics Letters, 370(3-4), p. 376-380||Publisher:||Elsevier Science||Place of Publication:||Amsterdam, Netherlands||ISSN:||0009-2614||Field of Research (FOR):||020201 Atomic and Molecular Physics||Peer Reviewed:||Yes||HERDC Category Description:||C1 Refereed Article in a Scholarly Journal||Statistics to Oct 2018:||Visitors: 190
