Radiative lifetime of the B¹Σ⁺ and b³Σ⁺ states of carbon monoxide

Author

Abstract

"The radiative lifetimes of the B¹Σ⁺ and b³Σ⁺ excited states of carbon monoxide were measured at six different pressures: 10, 25, 50, 75, 100, and 125 microns of Hg. The lifetimes were obtained by observation of the radiative decay of the (0,0), (0,1), (0,2), and (1,1) bands of the Angstrom system and the radiative decay of the (0,1), (0,2), (0,3), and (0,4) bands of the Third Positive system. No pressure dependence of the lifetimes was observed for either system. The average lifetime of the v' = 0 vibrational level of the B¹Σ⁺ state was found to be 24.4 x 10⁻⁹ seconds; that of the v' = 1 vibrational level of B¹Σ⁺ was found to be 23.9 x 10⁻⁹ seconds, and the average lifetime of the v' = 0 vibrational level of the b³Σ⁺ state was 57.6 x 10⁻⁹ seconds. All measurements are accurate to between 5% and 10% of the true value"--Abstract, page [i].
