Fourier Transform Spectra

High resolution Fourier transform spectra of the ν5 and ν8 bands of CD3C≡CH have been recorded and analyzed taking into account the strong x–y Coriolis interaction between these fundamentals. Fermi resonance of the ν8 state with the ν9 + ν10 state, l-type doubling interaction between the ± l components of ν8 and a weak k-type doubling interaction between the ν5 and ν8 states have also been included in the perturbation treatment. The parameters of the ν5 and ν8 states as well as some of the parameters of the unobserved ν9 + ν10 state have been determined. An estimate of the relative value of the transition moments has been obtained from the line intensities, which are strongly affected by the x–y Coriolis interaction.

Fourier transform spectra of the ν2 band of PH3 have been remeasured with 0.0045 cm-1 resolution. Ground state combination differences from these data have been fitted simultaneously with the microwave and submillimeterwave data to determine the ground state spectroscopical parameters of PH3 including the parameters of the Δk = ± 3n interactions. The correlation between the latter parameters has been discussed from the point of view of the existence of two equivalent effective rotational operators which are related by a unitary transformation. The ΔJ = 0, +1, ΔK = 0 (A1 ↔ A2, E ↔ E) rotational transitions in the ν2 and ν4 states have been measured for the first time by using a microwave spectrometer and a radiofrequency spectrometer with acoustic detection.

Seven Fourier transform spectra of the ν3 band of oxirane (ethylene oxide) have been recorded with different pressures and used to derive individual line intensities. These line intensities were satisfactorily fit leading to accurate transition moment constants. An atlas of line positions and intensities has been generated.
