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 BV | Place of Publication: | Netherlands | ISSN: | 1873-4448 0009-2614 |
