[Vibrational frequencies study of the hydroxy-benzoquinones].
In this paper, we report the Ab initio calculation and experimental investigation of the vibrational frequencies of 4,5-dihydroxy-1,2-benzoquinone and 2,5-dihydroxy-1,4-benzoquinone. The main IR and Raman absorption bands of them have been assigned, learned from other strong points to offset one weakness, by combination the program Gaussian 94 and MOPAC. The difference in absorption bands between them has been discussed.
