Abstract
Adsorbed layers of octanol and bromooctanol on top of formamide, are studied using core electron spectroscopy. In particular it is noted that the binding energy shift of the Br 3p line when going from a gaseous state to an adsorbed state is not the same for 2-bromooctanol and 8-bromooctanol. This is concluded to be mainly due to differences in polarisation energy. By applying a simple electrostatic mode1 of the polarisation energy, these findings suggest that the bromooctanol molecules are oriented at an angle smaller than 90° with respect to the surface.
