Fig 8. Variation contribution (%) from changes in N, Pi and N-Pi interaction on the lipid region (3020–2819 cm^-1, 1760–1726 cm^-1, 1475–1375 cm^-1, 1160–1149 cm^-1, 730–715 cm^-1) of FTIR-HTS spectra.

Variation contributions due to changes in N and Pi alone are presented in the first two rows (Var N and Var P), whereas contribution from N-Pi interaction (Int) is presented in the last row (Var Int).
