• The infrared spectra of halocyclohexanes and trans-1,2-dihalocyclohexanes trapped in thiourea channels were investigated by the use of the technique developed in the previous paper. It was revealed that these compounds took preferably the axial conformation of the C-X bond in thiourea channels. The abundance ratio of the two conformational isomers is found to depend upon the size and shape of these molecules and of the space provided by thiourea framework. From these results the bands attributable to the axial isomer were assigned definitely and the assignment made by previous workers was partly revised. The mobility or the orientation of these guest molecules in channels was also discussed and the dynamic equilibrium between the axial and equatorial conformations was proved in the case of halocyclohexanes.
