摘要: Using the phase‐shift method, a radiative lifetime study has been made of K2 B 1Πu molecule excited by 632.8‐nm line an He–Ne laser. The extrapolated to zero pressure is found be τ = 12.4 ± 0.3 nsec where error represents three standard deviations statistical uncertainty. A simple valence‐bond model for molecular transition proposed which predicts that state dialkalis will shorter, about factor 2 or more, than parent atomic P into alkali dimer separates. results these calculations are compared with experimentally observed lifetimes several vibrational states Na2 and K2.
