   <abstract xml:lang="ru">
    <p>Впервые выполнен квантово-химический расчет молекулы гексопреналина методами MNDO и AM1 с оптимизацией геометрии по всем параметрам стандартным градиентным методом. Получено оптимизированное геометрическое и электронное строение этого соединения. Теоретически оценена его кислотная сила (pKa=11). Установлено, что молекула гексопреналина относится к классу слабых H-кислот (9&lt;pKa&lt;14). </p>

    <p>First quantum-chemical calculation of the molecule of hexoprenaline by MNDO and AM1 methods with geometry optimization of all parameters by standard gradient method has been performed. The optimized geometric and electronic structure of this compound has been obtained. Its acid strength (pKa=11) has been theoretically evaluated.We have established that the molecule of hexoprenaline relates to a class of weak acids(9&lt;pKa&lt;14). </p>
