Microwave Fourier transform spectra have been measured for hydrazoic acid as its normal isotopomer, H¹⁴N₃, and two substituted isotopomers, H¹⁵N¹⁴N¹⁴N and H¹⁴N¹⁴N¹⁵N. The ¹⁴N quadrupole hyperfine structure has been resolved in all cases, and the quadrupole coupling constants of all ¹⁴N atoms have been determined. They are compared with those from ab initio predictions. Rotational constants A have been evaluated accurately for the first time for the two ¹⁵N species, and have been used to confirm a previously published structure
