CO2 laser Stark spectroscopy of the ν4 band of SiDF3: The C0 rotational constant and vibrationally induced dipole moment
TL;DR: In this paper, the CO2 laser Stark spectroscopy was applied to the SiF3 degenerate stretch (SiDF3) fundamental band of SiDF3, and it was found that electric field-dependent interactions of the (Δl, ΔK) = (2, −1) type, caused by the vibrationally induced dipole moment, give remarkable perturbations in the ν4 vibrational state.

CNDO-MO calculation of NnFm molecules
TL;DR: The s-p separation model CNDO-MO method has been introduced and developed for both the open and closed-shell systems since 1975 as mentioned in this paper, and it has been applied to the Coulombic repulsion integrals.

A Stark-effect microwave spectrograph of high sensitivity.
TL;DR: A microwave spectrograph is described in which the absorption of the gas being studied is modulated by the application of a periodic Stark‐effect field so that the output of the crystal detector contains a radiofrequency component which can be amplified with a narrow‐band amplifier.
