    The Stark effect in Rydberg states of a highly polar diatomic molecule: CaF by Petrovic, Vladimir S., Kay, Jeffrey J., Coy, Stephen L., Field, Robert W.

    Published 2011
    “…The Stark effect in molecular Rydberg states is qualitatively different from the Stark effect in atomic Rydberg states because of the anisotropy of the ion core and the existence of rotational and vibrational degrees of freedom. These uniquely molecular features cause the electric-field-induced decoupling of the Rydberg electron from the body frame to proceed in several stages in a molecule. …”

    METHODOLOGICAL ASPECTS OF INTERSPECIES EXTRAPOLATION OF EXPERIMENTAL DATA UNDER PULSED ACOUSTIC INFLUENCE ON BIOOBJECTS (REVIEW) by Nikolai N. Gavrish, Aleksey V. Bogomolov, Sergey K. Soldatov

    Published 2023-08-01
    “…An original hypothetical scheme for interpreting the effects of acoustic exposure in animals is proposed, which is suitable for obtaining threshold estimates of the levels of the adverse effect of the factor on clinical parameters in experimental animals, and vulnerable critical links in the regulation of external respiration in mammals that cause the damaging effect of acoustic vibrations are identified. A scientific and methodological approach to interspecies extrapolation of medical and biological effects of exposure to low-amplitude air pressure waves from animals to humans has been developed, taking into account the anatomical and physiological parameters of the respiratory system of experimental animals, as well as the informative characteristics of the acoustic pulse. …”
