Systematic Explanations of Bulbed Capillary Chemical Shifts of Benzene, Bromoform and Chloroform in Pure Liquids and Some Binary Systems Using Intramolecular and Intermolecular Effects

Abstract

Although the bulbed capillary chemical shifts of benzene, bromoform and chloroform are considerably varied in pure liquids and some binary systems, these shifts can be systematically explained as decided primarily by their «intrinsic» intramolecular effects and secondarily by their intermolecular effects. The intermolecular and intramolecular effects associated with the anisotropy effects of benzene and the electronegativity effects of bromoform or chloroform can be systematically understood from their crystal structure models. The intramolecular and intermolecular effects of the three species are evaluated numerically by systematically comparing their shift data with each other
