The resonance Raman spectra of irradiated and annealed at 185 K samples of P450 D251N in H2O buffer: spectra A (16O2) and B (18O2) and in the D2O buffer: spectra C (16O2) and D (18O2). The two bottom traces shows the difference spectra of 16O2-18O2 in H2O and 16O2-18O2in D 2O buffer (excitation at 442 nm, temperature 77 K).
