Abstract: The high-resolution FTIR spectrum of CF2=CH2 was measured and analyzed in the Fermi interacting v2 and v8 + v10 bands around 1735 cm-1. Both bands have strong infrared absorption with an A-type appearance. Watson's A-reduced Hamiltonian in the Ir representation was employed in the computation of the energy levels, taking into account the Fermi resonance contribution. A total of 2119 v2 transitions and 2056 v8 + v10 transitions were eventually assigned with a rms deviation of 0.00075 cm-1. In a nonlinear least-squares fit, accurate rovibrational constants of the upper states were determined with the band origins v2 = 1728.49829 ± 0.00005 cm-1 and v8 + v10 = 1741.50207 ± 0.00004 cm-1. Finally, a set of equilibrium rotational constants of CF2=CH2 were derived. © 1997 Academic Press, Inc.
