Using Fourier transform spectra recorded at 25 and 12 [mu]m, it has been possible to perform the first analysis of the 3[nu][sub 9] [minus] 2[nu][sub 9], 3[nu][sub 9] [minus] [nu][sub 5] and 3[nu][sub 9] [minus] [nu][sub 9] hot bands of HNO[sub 3] located at 392.4 cm[sup [minus]1], 409.8 cm[sup [minus]1], and 830.4 cm[sup [minus]1], respectively. An accurate description of the torsional splitting in the [nu][sub 9] = 3 vibrational state was achieved, leading to the determination of the two torsional band centers E[sub [nu][sub g]=3.1] = 1,288.8451 cm[sup [minus]1] and E[sub [nu][sub g]=3.2] = 1,288.9036 cm[sup [minus]1] and to the first determination of the [nu][sub 9] torsional potential of HNO[sub 3]. Finally, the 4[nu][sub 9] [minus] 3[nu][sub 9], [nu][sub 5] + [nu][sub 9] [minus] 2[nu][sub 9], and [nu][sub 5] + [nu][sub 9] [minus] [nu][sub 9] hot bands were identified for the first time at 375.3 [minus] 376.1 cm[sup [minus]1], 447.2 cm[sup [minus]1] and 885.424 cm[sup [minus]1] respectively.
