The high-resolution infrared spectrum of the v(HF)=2<--0 stretch in N-2-HF has been recorded using direct absorption of tunable infrared light in a slit jet spectrometer. The band origin is located at 7657.4057 cm(-1) red-shifted 93.39 cm(-1) from the v(HF) = 2<--0 Origin of the HF monomer. The changes in vibrational red shift with HF stretching quanta provide explicit information on the coupling between the high-frequency (i.e., intramolecular) and low-frequency (i.e., intermolecular) degrees of freedom, which can be understood with a simple electrostatic model. Additional evidence for coupling between the low- and high-frequency modes is provided through an analysis of the rotational consants. Specifically, rotational-RKR techniques are used to invert the spectroscopic data to provide one-dimensional potential curves for the intermolecular van der Waals stretch coordinate for the UHF = 0, 1, and 2 levels of N-2-HF. These potentials reproduce the experimentally observed increase in binding energy with incremental HF excitation. Homogeneous broadening of the rovibrational transitions is determined to be 79+/-11 MHz from a Voigt deconvolution of the individual absorption profiles and is independent of the upper state J within the experimental uncertainty. This broadening is attributed to a vibrational predissociation lifetime of 2.0+/-0.3 ns for the complex and reflects an ii-fold shorter vibrational predissociation lifetime than observed upon UHF = 1<--0 excitation in N-2-HF.
