The radiative lifetime of the <i>C</i> 3Π<i>u</i> state of N2

Abstract

New measurements of the radiative lifetime of the C 3Πu state of N2 have been made using the single photon delayed-coincidence technique. No significant variation of the lifetime with v′ having been found the proposed value is τ = (39.2±3.9)ns. This is in good agreement with published values that we consider as the more reliable ones following the criteria discussed in this paper.
