The high-resolution (2.3 × 10−3 cm−1) Fourier transform infrared spectrum of PHD2 was recorded for the first time and analyzed in the region of the three lowest bands belonging to the three bending fundamentals. Between 1100 and 1800 transitions were assigned to each of the ν3, ν4, and ν6 bands and 1267 upper energies were obtained thereof. These were fitted by 58 parameters, which reproduce the experimental upper energies with rms deviations of 1.3 × 10−4 cm−1 and 2.7 × 10−4 cm−1 for the J ≤ 17 and J ≥ 18 levels, respectively.
