N2 - In a molecular beam, laser-induced fluorescence experiment, rotational spectra of the A**3 PI , v equals 0 implied by X**3 SIGMA , v equals 0 transition of the NH free radical were measured at 336 nm with high resolution. From more than 300 completely resolved hyperfine lines the hyperfine structure of the A**3 PI excited state and the X**3 SIGMA ** minus ground state could be analyzed. For the first time, the hyperfine coupling constants a//N//,//H, b//N//,//H, c//n//,//H,d//n//,//H,eQq//1, and eQq//2 in the A**3 PI state were determined. Also, the nuclear quadrupole coupling constant eQq//1 in the X**3 SIGMA ** minus ground state was obtained.
