摘要：

The resonance Raman spectrum of tetrathiosquarate was investigated, revealing a very substantial enhancement of the Raman band at 1075 cm-1, assigned to the v(C = C + C = S) mode of the B1g species. The selective enhancement of this mode, the absence of enhanced totally-symmetric modes and the dispersion of the depolarization ratio are very strong indications that in tetrathiosquarate the Jahn-Teller effect is operative, as already verified for the parent ion squarate.
