✦ Synopsis

A total of 6071 transition wavenumbers of the 2 , 3 , 5 , and 6 fundamental bands of H 3 13 CF and 1689 frequencies of the rotational transitions in the v 2 ϭ 1, v 3 ϭ 1, v 5 ϭ 1, and v 6 ϭ 1 vibrational states have been fitted simultaneously by taking into account various Coriolis interactions, l-type interactions, and ␣-resonance terms between and within the vibrational states. The standard deviation of the fit using 75 parameters was ϭ 7.63 ϫ 10 Ϫ5 cm Ϫ1 for the infrared data and 0.150 MHz for the rotational data. The possibility of obtaining a quantitative fit of the very precise data of high-resolution Fourier transform and submillimeter-wave spectroscopy for a semirigid symmetric top molecule is discussed.

The high-resolution FTIR spectrum of CF 2 |CH 2 was measured and analyzed in the Fermi interacting n 2 and n 8 / n 10 bands around 1735 cm 01 . Both bands have strong infrared absorption with an A-type appearance. Watson's Areduced Hamiltonian in the I r representation was employed in the computatio

The infrared spectra of 16 O 3 have been recorded in the 3700 cm 01 region, with a Fourier transform spectrometer at 0.008 cm 01 resolution. A White-type cell, ᐉ Å 32.16 m, filled with 42.8 Torr O 3 was used. This spectral region corresponds to the n 2 / 3n 3 and n 1 / n 2 / 2n 3 bands. The n 2 / 3n

Using a Fourier transform spectrometer, we have recorded the spectra of ozone in the region of 4600 cm 01 , with a resolution of 0.008 cm 01 . The strongest absorption in this region is due to the n 1 / n 2 / 3n 3 band which is in Coriolis interaction with the n 2 / 4n 3 band. We have been able to a
