Investigation of the liquid vapour shift in the infra-red absorption frequency of diatomic molecules

The changes in the infra-red absorption frequency of three diatomic molecules, HCl, HBr and CO, on the transition between the gaseous and the solution phase have been investigated experimentally. The magnitude of this shift has been predicted using a purely electrostatic interaction. The experimental values and predicted values for HCl agree within 17%. The experimental and predicted values for HBr and CO agree within an order of magnitude. The investigation provides a method for independently checking the variation of the dipole moment of these molecules with internuclear distance against values previously determined by infra-red intensity measurements. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
