title: [Raman spectral study of nitrosyhemoglobin and several other hemoglobins].
abstract: The Raman spectra of nitrosyhemoglobin (NOHb), methemoglobin (MetHb), oxygenated hemoglobin (oxyHb), and deoxygenated hemoglobin(deoxyHb) were comparatively studied. The results show that the Raman spectra with 632.8 nm excitation can be used to detect the R state (oxyHb) to T state (deoxyHb) transition. The difference of NOHb and MetHb in their electron spin state was clearly demonstrated in their Raman spectra with 632.8 nm excitation, suggestingthat Raman spectra provide anew simple way to measure and distinguish NOHb and MetHb.
