Abstract:
The fine and hyperfine structure of the (0, 0) band of the B2Sigma+u-X2Sigma+g system of 14N+2 has been measured using fast-ion-beam laser spectroscopy. Rotational transitions with 0 /= 3, together with the complete rotational line profiles for N" < 5, were used to determine the spin-rotation constants and the Fermi and dipolar hyperfine constants for the B and X states. This is the first time the hyperfine constants for v" = 0 have been measured for gas-phase N+2. Copyright 1998 Academic Press.
