Photoisomerization of Halogenodimethyl Sulfides Photolysis of iodo‐ ( 3a ), bromo‐ ( 3b ), and chlorodimethyl sulfide ( 3c ) in an argon matrix at 12 K gives rise to isomeric species 4a — c. Ab initio calculations indicate that in these isomers the halogen has been removed from the carbon atom and forms a weak bond to forms a weak bond to the sulfur atom. This conclusion is based on the comparison of observed and calculated IR spectra of the photoisomers.
