In an attempt to account for the large-amplitude torsional \(\nu_{9}\) mode of nitric acid, a formalism is set up, based on an internal-axis-method-like approach previously developed for high-barrier tunneling problems. This formalism is applied to the calculation of the tunneling-rotationalvibratio
Using Fourier transform spectra recorded at 25 and \(12 \mu \mathrm{m}\), it has been possible to perform the first analysis of the \(3 \nu_{9}-2 \nu_{9}, 3 \nu_{9}-\nu_{5}\) and \(3 \nu_{9}-\nu_{9}\) hot bands of \(\mathrm{HNO}_{3}\) located at \(392.4 \mathrm{~cm}^{-1}\), \(409.8 \mathrm{~cm}^{-1}
The high-resolution FTIR spectrum of the n 8 / n 9 band of HNO 3 around 1205 cm 01 has been measured and analyzed. The bright state was found to be strongly perturbed by its neighboring dark state n 6 / n 7 at the coincident levels. Taking account of the DK Å {2 anharmonic resonance, a simultaneous
