Lifetimes of the Electronic-Vibrational-Rotational States of Hydrogen Molecule (Review)

摘要

Data on the lifetimes of the vibrational-rotational levels of the excited electronic states of hydrogen molecule (including H_(2), D_(2), HD, DT, and T_(2) isotopomers) are reviewed. All data on the rotational sublevels of the lowest vibrational levels of various electronic states are presented, which were available before June 2001. A comparative analysis of the data obtained by various researchers using different methods (experimental, semi-empirical, and non-empirical) is performed for the first time. The influence of non-adiabatic intramolecular interactions on the dependence of lifetimes of the rovibronic levels of hydrogen molecule on the vibrational and rotational quantum numbers is discussed. A set of reliable data is selected which can be recommended for use in various applications.
