Используется оператор кинетической энергии общего вида для произвольных обобщенных координат. Показано, что для трехатомной нелинейной молекулы движения разделяются точно. Задача о многоатомной молекуле сводится к “трехатомной”.</p></abstract><trans-abstract xml:lang="en"><p>A new method for solving the problem of separation of vibrational and rotational motions in a molecule is proposed and a formula for rotational energy levels is derived. The general form of kinetic energy operator for arbitrary generalized coordinates is used. It is shown that the motions are separated exactly for a triatomic nonlinear molecule. The problem of a polyatomic molecule is reduced to the triatomic one. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>квантовая теория молекул</kwd><kwd>разделение колебаний и вращений</kwd><kwd>вращательные уровни энергии</kwd><kwd>quantum theory of molecules</kwd><kwd>separation of vibrations and rotations</kwd><kwd>rotational energy levels</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">М.
