英文摘要	two chiral sulfur compounds, tert-butyl tert-butanethiosulfinate (1) and tert-butanesulfinamide (2), with inversion of configuration, have been studied by raman optical activity (roa) and electronic circular dichroism combined with density functional theory calculation. with the ss linkage in 1, the couplings between the two tertiary carbon atoms often generate large roa signals, whereas the tertiary carbon atom itself generally makes a large contribution to roa signals in 2 for similar vibrational modes. the conformational dependence of roa parameters provides probing conformation around the ss bond from a new perspective. the simultaneous use of electronic circular dichroism and roa is warranted to extract reliable conformational information. roa provides a suitable candidate for the stereochemical study of chiral sulfur compounds, especially its capability of sensing the conformation around the ss bond. chirality 24:731740, 2012.
