Abstract
The vibrational circular dichroism (VCD) of various amino acid derivatives have been recorded on an FTIR spectrometer in the carbonyl stretching region. In particular, N-tert-butyloxycarbonyl-alanine has been investigated in solvents of different polarities and hydrogen-bonding characteristics (water, dimethyl-sulfoxide, and deuterochloroform). This molecule shows a strong couplet in solvents of low polarity and displays no VCD activity in an aqueous environment. The results of coupled oscillator calculations for this and other molecules will be discussed.
