| Abstract: | The infrared and Raman spectra of some chloroquinones have been obtained and compared with the spectrum of para benzoquinone. Vapour, solution and crystal phase data are presented. The complete vibrational assignment of p-benzoquinone has been made [1], and this has been used to aid the assignment of the chloro derivatives. The 2,5 dichloro derivative is considered in some detail and the results for the 2,6 and the tetra-chloro compounds are briefly summarised. The bonding within these structures is discussed. |
