Abstract: A comparative study of adiabatic, diabatic, and Born-Oppenheimer approximation in molecular systems is made. A misthod to reveal the breakdown of the Born-Oppenheimer approximation is examinated and a procedure to determine, from precise experimental data, the charastsristic parameters of the extension of the breakdown is showed. Finaily the isotopic effect in potencial curve, derived of the inapplicability of the Born-Oppenheimer approximation in some molecules is studied.
