| contents | We report the measurement of radiative lifetimes of the $6^1Σ_g^+(v=9,J=31)$ state of gas-phase molecular sodium using a high-resolution double-resonance spectroscopy. Measurements were done using a time-correlated photon counting technique at various pressures and temperatures. Lifetimes were extracted from extrapolations to the zero buffer gas pressure, called Stern-Volmer plot, and the temperature-dependence of the radiative lifetimes were measured over a temperature range from 593 K to 653 K. Our result agrees well within the error limits with the theoretical calculations. |
