The effect of plasma Coulomb microfied dynamics on spectral line shapes is under consideration. analytical solution the problem unachievable with famous Chandrasekhar–Von-Neumann results up to present time. alternative methods are connected modeling a real ion field by approximate models. One most accurate theories ions in plasmas Frequency Fluctuation Model (FFM) tested comparison microfield n...

The vibrational Stark effect measures the effect of an external electric field on the vibrational (IR) spectrum of a molecule. This technique gives quantitative information on the sensitivity of a vibrational peak position to an electric field. This calibration can be used to evaluate shifts in the vibrational frequency caused by changes in the local electric field in the organized electrostati...
