Abstract
 
 
The absorption spectra of SnI₄, SuBr₄, SnCl₄, SnBr₂, C₂I₄, C₂I₂, C₂H₄I₂, CH₂I₂ have been measured in various solvents. It is shown that results of previous workers for SnI₄ have been subject to errors due to decomposition of the compound. This decomposition was prevented in the curves obtained in this work. The decomposition could not be stopped in the case of SnBr₄ and a hypothesis is put to explain this difference in the behaviour of SnI₄ and SnBr₄.
 
The spectra of the iodine compounds are discussed on the basis pf the theory that in compounds containing several iodine atoms and weak X - I bonds part of the absorption is due to interaction between the iodine atoms.
 
The effect of change of solvent on the absorption of the carbon compounds was studied and a tentative explanation put forward.
