Molecular beam laser Stark spectroscopy has been used to measure the υ = 3 vibrational state dipole moment of hydrogen fluoride as 1.9614 ± 0.0021 debye. This measurement allows μυ to be expressed as a power series expansion in [Formula: see text] without the use of infrared intensity data. A detailed comparison is made with similar series based mainly on infrared intensity data and more recent ab initio calculations.

Saturated absorption spectra of four different transitions in the ν2 fundamental bands of H217O and H218O have been observed using the technique of intracavity CO laser Stark spectroscopy. The analysis of these spectra yields a direct measurement of the dipole moment change between the ground vibrational state and the ν2 = 1 state of H217O, as well as the zero-field frequencies for the observed transitions. A collision-induced centre dip ('crossover resonance') which occurs in one spectrum is formed in a four-level system that is probably the most nearly isolated of any yet observed.

The 9–8 P(13) line of the 12C16O laser (1884.349 cm−1) has been used to study laser Stark Lamb dip spectra associated with the R(3/2) line of the rotation–vibration fundamental band of NO. We have observed fully resolved hyperfine structure (line width ≈ 500 kHz) due to both components, Ω = 3/2 and 1/2, of the 2Π ground state. In addition, two level crossing signals have been observed in the v = 1 vibrational state of the 2Π1/2 component. The values we obtain for the electric dipole moment (in Debye) are:[Formula: see text]It was possible to determine μ′ and μ″ separately for the 2Π1/2 component because of the observation of the level crossing signals, which depend only on μ′. Our result for μ″ of 2Π1/2 agrees, within error limits, with a more precise previous measurement by molecular beam techniques, and our other results are more precise than previous determinations based on infrared intensities.
