Laser induced D ^1Π-a^3 fluorescence of the nak molecule - Chiu, C.-L.; Chang, H. (Elsevier)
Five systems of the D ^1Π-a^3^+ transition of NaK molecules, assigned as α, β,γ, δ and ε are observed with various single mode 4765 Å argon ion laser line excitations Among them, only system α had been reported and analyzed previously. The headsof these systems are at 15978, 16610, 16857, 16914 and 16671 cm^-^1, respectively The estimated upper and lower vibrational levels for these systems are ν' = 12, 22, 31 +/- 2, 35 +/- 2 and 24 +/- 2 of the D ^1Π state and ν'' = 0, 5, 8 +/- 1, 9 +/- 1, and 6 +/- 1 of the X^1 state.
