Abstract
The highly precise measurements of Stark coefficients in the lambda doubling transitions of a 3Π CO obtained in previously published molecular beam electric resonance experiments have been reanalyzed. Certain perturbations between vibrational levels of the a 3Π and a’ 3Σ+ states that were neglected in the earlier treatment have been found to be important. An apparent error, by a factor of in the Stark matrix elements that were used in prior work, has also been corrected. The previously reported experimental determination of the dipole moment function of a 3Π CO is shown to be invalid. Thus, the relatively flat appearance of the dipole moment function found in previous ab initio studies may indeed be correct. The dipole moment in the a’ 3Σ+ state and the transition moment between the a 3Π and a’ 3Σ+ states are substantially revised to −0.79 and +0.64 D, respectively.

Vibrationally exciting molecules trapped on a microchip

TL;DR: In this article, the transition between two vibrational quantum states can be induced while the molecules are trapped above the chip using CO molecules, prepared in the J'='1' rotational level of the 3Π1, v' ='0 state and induced by pulsed, narrowband IR radiation.

Fine Structure, Dipole Moment, and Perturbation Analysis of a 3Π CO

TL;DR: In this paper, a least square fit to optical and radio-frequency data on a 3Π state of carbon monoxide from 5 to 1000 MHz has been performed using a molecular beam electric resonance spectrometer, where the vibrational dependence of the constants which determine the lambda doubling in the a 3 Π state is accounted for.

Radio‐Frequency Spectrum of the a3Π State of Carbon Monoxide

TL;DR: In this article, a preliminary investigation of the molecular-beam electric resonance spectrum of the metastable a 3Π state of 12C16O is reported, and the electric dipole moment observed is 1.38±0.02 D. The variation of dipole moments with vibrational state appears to be less than 0.005 D per vibration.
