We reexamine the N = 3 valence excitations of (HF)(2) and their combinations with intermolecular vibrations using a high-sensitivity germanium detector which collects the first overtone emission of fragment HF. We use the specific vibrational product state production to assign the quantum numbers within a vibrational polyad. The band previously assigned to K = 1 of nu(1) + 2 nu(2) (J. Chern. Phys. 1994, 100, 1) is shown to originate from K = 1 of 3 nu(2) + nu(6). This assignment, based on photofragment HF vibrational state, is supported by the observation of quenched hydrogen interchange tunneling (Delta nu(1) = -0.6 GHz) and rapid vibrational predissociation [Delta nu(pd) = 3.5(10) GHz] of this state. The K = 1 band origin of the lower A(-) level is 11 537.047(6) cm(-1). The rotational constants for the two tunneling components are the same within experimental error, ((B) over bar)=0.2182(2) cm(-1). The out-of-plane vibration frequency, 3 nu(2)+nu(6)-3 nu(2) = 493.96(3) cm(-1), is increased 25% from the ground state. The predissociation rate of this combination state is a factor of three slower than that observed at 3 nu(2). The combination mode 3 nu(1)+nu(4) has band origins of nu(0)= 11 402.889(4) and 11 402.867(8) cm(-1) and rotational constants of (B) over bar = 0.216 39(17) and 0.217 04(15) cm(-1) for the two tunneling components A(+) and B+, respectively. The tunnel splitting Delta nu(t) = nu(0)(B+) -nu(0)(A(+)) -0.021(8) cm(-1). The frequency of nu(4) the intermolecular or hydrogen bond stretching vibration, 3 nu(1) + nu(4) - 3 nu(1) = 129.36 cm(-1), is quite similar to that at nu(1), suggesting only a minor dependence of the hydrogen bond vibration on the free-HF bond length. The 3 nu(1) + nu(4) band has a predissociation linewidth of 2.5(2) GHz, one order of magnitude larger than the 0.24(2) GHz of the pure overtone 3 nu(1) state. The coupling of this level to the dark state 3 nu(2) + nu(4) + nu(5) is suggested as the origin of the observed linewidth increase.
