Аннотация:

Предложено аналитическое описание тензора динамической электронной поляризуемости αii(R, ω) двух-атомных молекул LiH и Li2 как функций их межъядерного расстояния R и частоты внешнего электромагнитного поля ω. Описание базируется на оценках верхних и нижних границ αii(R, ω), которые рассчитываются с помощью известных функций статической поляризуемости молекулы αii(R, 0), конечного числа энергий возбужденных электронных состояний молекулы Em(R) и моментов электродипольных переходов (di)0m(R).
