✦ Synopsis

Of the gas-phase IR spectrum of nitrylfluoride, FNO 2 , between 1200 and 1900 cm Ϫ1 , the bands 4 , 2 6 , 2 ϩ 3 , and 1 have been studied at a resolution of ca. 0.003 cm Ϫ1 . Improved ground state rotational and centrifugal distortion constants have been obtained from a simultaneous analysis of the data from F. Hegelund, H. Bu ¨rger, and G. Pawelke [J. Mol. Spectrosc. 184, 350 -361 (1997)] and the present data from 4 and 1 . The 4 and 2 6 bands are free from local perturbations, and upper state spectroscopic constants have been obtained from the conventional Watson Hamiltonian. The bands 1 and 2 ϩ 3 are strongly perturbed by Coriolis interactions with the nearby dark levels 5 ϩ 6 , 3 ϩ 6 , and 2 ϩ 5 . Upper state constants for 1 and 2 ϩ 3 are obtained from triad and tetrad models, respectively, including Coriolis resonances within this system. In addition Coriolis interaction parameters and the vibrational energies for the three dark states together with some of their rotational constants are determined from the observed perturbation effects on 1 and 2 ϩ 3 .
