АннотацияЖурнал физико-химического профиля. Адресован специалистам, работающим в области квантовой химии, физических методов исследования, кристаллохимии, супрамолекулярной химии, структуры и свойств наноматериалов, строения жидкостей, а также широкому кругу химиков. Своеобразие журнала заключается в том, что для исследования электронного и пространственного строения химических соединений в публикуемых работах широко применяются современные физические методы, оригинальные теоретические и экспериментальные подходы. Форма публикаций - статьи, краткие сообщения, тематические обзоры по различным проблемам структурной химии. С 2004 г. Издаётся ежегодное Приложение к Журналу, в котором публикуются статьи по актуальным направлениям структурной химии. Журнал переводится на английский язык, издается и распространяется за рубежом Издательством Springer. Название англоязычного издания Journal of Structural Chemistry.

P. 299. 2011. 52, 4 . 686 695 UDC 541.6:546.29 A COMPARATIVE STUDY OF INTERMOLECULAR POTENTIAL ENERGY FUNCTIONS PROPOSED FOR THE RARE GAS DIMERS 2011 R. Islampour*, M. Gharibi, A. Khavaninzadeh Department of Chemistry, Tarbiat Moallem University, 49 Mofateh Avenue, Tehran, Iran Received March, 5, 2010 The vibration-rotation energy level spacings of homo- and heteronuclear rare gas dimers are calculated for some more common analytical intermolecular potential energy functions in a unified way by employing the discrete variable representation (DVR) method. <...> K e y w o r d s: rare gas dimers, DVR method, vibration-rotation energy levels. <...> Since the dispersion attraction increases as the atomic size increases, the well becomes deeper as the dimer size increases. <...> This is due to the asymptotic nature of the dispersion expansion, which is only valid for the distances where charge distributions do not overlap, and thus lack of a term that accounts for the overlapping region. <...> To eliminate these unrealistic behaviors we may either define a piecewise function by restricting the range of validity of the potential or introduce a damping function in the attractive part of the potential. <...> In the following we shall briefly describe some more common potential functions devised, by taking equation (1) as the starting point, for the inert gas dimers from experimental data or theoretical calculations. * E-mail: islampour@tmu.ac.ir A COMPARATIVE STUDY OF INTERMOLECULAR POTENTIAL ENERGY FUNCTIONS PROPOSED FOR THE RARE GAS DIMERS 687 i.
