- Abstract
- We measured the FT spectrum of natural FCN from 1200 to 1800 cm-l and from 2800 to 1000 cm(-1) with a near Doppler resolution and a line-position accuracy between 1 and 8 x 10(-4) cm(-1). Lines were assigned to 91 different bands (75 of (FCN)-F-19-C-12-N-14, 11 of (FCN)-F-19-C-13-N-14, and 5 of (FCN)-F-19-C-12-N-15), Of which no more than five had been previously reported at lower resolution. From band-by-band analyses we deduced effective state parameters. As those results complete the study of the Fourier transform spectra of natural cyanogen fluoride from 1200 to 7000 cm(-1), global rovibrational analyses of (FCN)-F-19-C-12-N-14, (FCN)-F-19-C-13-N-14, and (FCN)-F-19-C-12-N-15 have been performed on the basis of all the available experimental data about their rovibrational energies, We have so determined sets of about 100 molecular parameters for each isotopomer, and a statistical agreement was obtained. A labeling of the vibrational states is proposed on the basis of the ei,eigenvector coefficients.
