Abstract: 
Using a newly constructed Fourier transform emission apparatus, we have measured the threefold substituted HCN isotopomer, (DCN)-C-13-N-15, at 1370 K in the range from 450 to 700 cm(-1). We could assign hot bands with upper states up to nu(2)(1) = 12(12). The assignments have been verified for states up to nu(2) = 5 by fitting with earlier room temperature absorption measurements of overtone and hot bands. The intensities are shown to be in qualitative agreement with the expected intensity pattern for such emission spectra. All the measurements for (DCN)-C-13-N-15 have been combined in a single least-squares fit that includes approximately 2700 rovibrational lines which have a root-mean-square deviation on the order of 0.000 4 cm(-1). The spectroscopic constants for the bending states nu(2) = 1,...,12 are reported, as well as for some combination states involving the other vibrational modes. We also give the spectroscopic constants of various states of DCN, (DCN)-C-13-N-14, and (DCN)-C-12-N-15 which where obtained from room temperature absorption measurements, (C) 1999 Academic Press.
