| Abstract: | The vibrational spectra of iodine and bromine thiourea charge transfer complexes in the solid state were obtained. The Raman spectrum shows a very strong band at 215 and 255 cm−1, for the iodine and bromine complex respectively.In the case of iodine, the vibrational spectrum can be interpreted on the basis of the structure proposed by the X-ray study. The data obtained in the present investigation, strongly suggest that the bromine complex has a similar structure, albeit smaller stability. |
