The circular dichroism spectrum of S(+)-sec-butyl benzene

The absorption and CD spectra of S(+)-sec-butyl benzene are reported in the spectral region 195–180 nm. The CD spectrum contains two bands of opposite sign at 190.5 nm and 187 nm. The results are interpreted to confirm previous results for 1-methylindan in this spectral region. The observed bands are assigned to the state derived from the benzene E_2g state.
