Show affiliationsSoft X-ray natural circular dichroism (SXNCD) spectra of serine (Ser) and alanine (Ala) thin films, were measured in absolute value with the focus at the oxygen 1s → π* transition of COO-. In the case of L-Ser, a positive and negative SXNCD peaks were observed around 531.5 and 532.5 eV, respectively. In the case of L-Ala, a negative SXNCD peak was observed around 532.8 eV. The SXNCD intensity of L-Ala was about ten times as large as that of L-Ser. Those differences would reflect the chiral environment of the core hole oxygen atoms of COO-.
