Figure 5.
(A) 77 K rR spectra of WT Az (black line, 647.1 nm), F114P Az (red line, 600.0 nm), N47S Az (green line, 647.1 nm) and F114N Az (blue line, 647.1 nm). (B) Expanded region containing Cu-S vibrations; lines mark the positions of intensity-weighted average, <νCu-S>, of peaks L, M, N, O. <νCu-S> is the same for WT and F114N Az.
