A Simple Relation among the Energy Differences between Conformers of XH2C-CH2Y, C6H11X, C6H11Y, and trans-1,2-C6H10XY

摘要: By measuring the infrared intensities, energy differences between two conformers have been determined for bromocyclohexane, iodocyclohexane, trans-1-bromo-2-chlorocyclohexane, 1-bromo-2-chloroethane, ethylene bromohydrin, and iodohydrin in dilute solutions, cyclohexanol, trans-2-chlorocyclohexanol, chlorohydrin, bromohydrin vapors.It was ascertained that following relation holds differences:Et−Eg=(Eaa−Eee)−(Ea−Ee)−(Ea′−Ee′).Here Et−Eg is difference trans gauche isomer of XH2C–CH2Y, Eaa−Eee aa- ee-isomer trans-1,2-C6H10XY, Ea−Ee Ea′−Ee′ are those a- e-isomers C6H11X C6H11Y respectively, where X a halogen Y or O–H group.
