Abstract
The infrared and Raman spectra of the three crystalline modifications of hydroquinone (HQ), known as alpha-HQ, beta-HQ and gamma-HQ, have be en measured and compared with the spectra of HQ solutions. The spectra have been assigned on the basis of a normal coordinate analysis of th e molecule and a factor group analysis of the crystals. The hydrogen b onds are relatively the strongest in beta-HQ, the weakest in gamma-HQ.
