✦ Synopsis
The high-resolution FTIR spectrum of acetylene in the (\sim 3800 \mathrm{~cm}^{-1}) region has been analyzed for various hot bands originating from the low-lying (v_{4}) and (v_{5}) bending modes. The data have been fitted to a second-order transformed Hamiltonian which includes appropriate off-diagonal terms to account for vibrational and rotational (l)-type resonances. Parameters for various stretchbend combination levels, which fit the data with residuals (\left(\sim 2.5 \times 10^{-4} \mathrm{~cm}^{-1}\right)) approaching the experimental accuracy, are reported. c 1995 Academic Press, Inc.

The hot band structure of the high-resolution Fourier transform spectra of monoiodoacetylene measured in the region of the bending fundamental n 1 4 (600-655 cm 01 ) with a resolution of 0.0020 cm 01 has been studied in detail. In addition, three spectra n 4 / n 5 0 n 4 (180-320 cm 01 ), 2n 0 4 (122
Fourier transform emission spectra were recorded using a mixture of H 2 O and D 2 O at a temperature of 1500 • C. The spectra were recorded in three overlapping sections and cover the wavenumber range 380-2190 cm -1 . A total of 22 106 lines were measured, of which 60% are thought to belong to HDO.
