| Abstract | The high-resolution Fourier transform infrared spectrum of the ν6 and ν7 bands of deuterated nitric acid (DNO3) has been measured in the region between 510 and 667 cm−1 . The rovibrational transitions of both bands have been assigned and analyzed. Slightly improved ground state constants have been determined. The ν7 band is centered at 541.5847 ± 0.0002 cm−1. It shows no sign of perturbations and has been fit through J = 64 with an rms deviation of 0.0002 cm−1. The ν6 band is centered at 642.1383 ± 0.0002 cm−1 and is perturbed by 2ν9 through a Fermi resonance term and possibly a Coriolis term. The resonance is particularly noticeable above J = 40, where a crossing of rotational levels of the two vibrational states leads to a ΔK ± 2 interaction. A hot band centered at 632.7081 ± 0.0005 cm−1 has also been analyzed and identified as due to (ν6 + ν9) − ν9. |
