Hyperfine quantum beat spectroscopy has been combined with an effective Hamiltonian approach to determine the hyperfine structure of NO ( A, v ). NO ( A, v = 0, N = 1–7, 9 J = 1.5–8.5, F = 0.5–8.5) was produced by pulsed dye laser excitation on the 0–0 band of the NO A2 Σ + ← X2 Π transition at wavelengths around 226 nm.
