The a-type $K=0$ microwave spectrum of the $N2-H2O$ complex has been observed-$K=0$-microwave spectrum of the $N2-H2O$ complex has been observed using a pulsed molecular beam Fabry-Perot cavity microwave spectrometer. Seven isotopic species have been studied in the range of 5-23 GHz. The $N2-H2O$ complex exhibits tunneling motions similar to the $1\to 2$ tunneling motion of the $H2O-DOD$ complex1 which gives rise to four components for each rotational transition. The molecular constants obtained for $\mathrm{<mrow\; data-mjx-texclass="ORD">14</mrow>}N2-HOH$ are (in MHz): [FIGURE] The structure has a nearly linear N-N-HO geometry with a N-H distance of 2.42(4)A and an OHN angle of $168\circ$ (RON = 3.37(4)A). The electric dipole moment along the principal axis was determined for the $\mathrm{<mrow\; data-mjx-texclass="ORD">15</mrow>}N2-H2O$ species with $\mu a=0.833(3)$ Debye.
