Comparison of 230 nm-excited UVRR F-R difference spectra. F-R difference spectra of Hb S (top), NEM-H Hb (center) and NEM-L Hb (bottom), obtained with 230 nm excitation. Samples were 1.0 mM Hb, in 1.0 M potassium phosphate buffer, pH 7.1. Fibers were formed by initiating a temperature jump from 10-35 °C.
