Abstract
The rovibrational spectrum of N2--D2O complex was measured in the v2 bend region of D2O using a rapid-scan diode laser spectrometer to probe a pulsed supersonic slit jet. Three subbands, namely Ka = 1--0, 0--0, and 0--1, were recorded. All the transitions in the spectrum are doubled, due to D2O tunneling within the complex. The spectrum was analyzed in terms of a standard asymmetric rotor Hamiltonian, yielding band origins, rotational and centrifugal distortion constants for the upper and lower tunneling levels. The band origin of N2--D2O is slightly blue-shfited from the monomer, indicating that the intermolecular bond becomes weaker upon vibrational exciation of the v2 bend mode of D2O. The tunneling dynamics within the complex will be discussed.
