The resulting expression contains series with terms depending on the gradually growing up with the time number of spins in clusters of correlated spins. The influence of the possible degradation of these clusters on the shape of the spectra is taken into account. Analytical and numerical calculations were performed for various parameter values included in the final expressions. The developed theory adequately describes the results of numerical calculations of the MQ spectra performed by us and experiments: the transformation of the Gaussian profile into an exponential one, the asymptotics (wings) of the spectrum depending on the coherence order <italic>M</italic>, the dependence of the relaxation rate of the MQ spectrum on <italic>M</italic>, as well as the narrowing and stabilization of the MQ spectrum under the influence of perturbation.</p></abstract><trans-abstract xml:lang="ru"><p>Развиваемая в работе статистическая модель, позволяет с помощью разложения искомых временных корреляционных функций по бесконечному набору ортогональных операторов и использования некоторых известных фактов из физики традиционных модельных систем рассчитать форму (профиль) спектров многоквантового ЯМР (зависимость амплитуд соответствующих многоквантовых когерентностей от их порядков). Полученное выражение содержит ряды по растущему числу спинов в кластерах коррелированных спинов в зависимости от времени. Учтено влияние возможной деградации указанных кластеров на форму спектров. Для различных значений параметров, входящих в окончательные выражения, выполнены аналитические и численные расчеты. Представленная теория адекватно описывает результаты численных расчетов многоквантовых спектров и экспериментов: трансформацию Гауссова профиля в экспоненциальный при увеличении порядка когерентности <italic>М</italic>, т.е. при переходе от центра спектра к крылу, зависимость скорости релаксации многоквантового спектра от <italic>М</italic>, а также его сужение и стабилизацию МК спектра под действием возмущения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>spin</kwd><kwd>radiospectroscopy</kwd><kwd>multiple quantum NMR</kwd><kwd>paramagnets</kwd><kwd>quantum technology</kwd><kwd>spin dynamics</kwd><kwd>multiple spin correlations</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>cпин</kwd><kwd>радиоспектроскопия</kwd><kwd>многоквантовый ЯМР</kwd><kwd>парамагнетик</kwd><kwd>квантовые технологии</kwd><kwd>спиновая динамика</kwd><kwd>многоспиновые корреляции</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">N.
