The rovibrational spectra of N2-D2O, N2-DOH and N2-H2O were measured around the 1 OD and 2 OH stretching regions. A combination band involving the intermolecular in-plane N2 bending vibration was also observed in each spectral region. The bands observed around the 1 OD stretching region were measured at the University of Calgary using a pulsed-slit supersonic jet expansion and a mid-infrared tunable optical parametric oscillator. The N2-H2O spectra were measured at the UCLouvain using the FANTASIO+ setup [1,2]. The spectra were analyzed by considering the feasible tunneling motions and fit to a series of independent asymmetric rotors. The rotational constants of the four tunneling components of N2-D2O and N2-H2O were retrieved for the excited vibrational states. The tunneling splittings are discussed as a function of the vibrational state and the nature of the isotopologues.
