Abstract
From very high resolution (8 MHz FWHM) LIF measurements, the hyperfine coupling constants of N2(A 3Σ + u ) and N2(B 3Π g ) have been obtained for three pairs of vibrational quantum numbersv′,v″. TheA-state constants are in very good agreement with accurate literature data. The vibrational dependence of some of theB-state constants is found to be much more pronounced. This is qualitatively explained in terms of the electronic structure of the two states.
