THE FT-IR SPECTRUM OF (HCNO)-N-15 - THE NU(1)-BAND, NU(2)-BAND, 2-NU(3)-BAND, AND NU(2)+NU(3)-BAND SYSTEMS

The infrared spectrum of HC15NO an isotopically substituted species of fulminic acid, has been measured in the range 1900-3600 cm-1 at a resolution of 0.003 cm-1 with a Bruker IFS 120 HR interferometer. More than 100 subbands have been assigned. Power series coefficients for these transitions are given. A Coriolis resonance between the levels 01002 (l = 0e) and 01010 (l = 1e) allows normally "forbidden" transitions to occur, some of which were observed and assigned. We correlate transition intensities and energies of the resonance system. Variations in the manifold of nν5 states with excitation of other modes are compared. © 1993 Academic Press, Inc.
