Fig. 9. Resonances (first derivative curves) of x-irradiated hair compared with 



similar resonances for cystine and cysteine. Mariner spacing at base, 68 gauss. 



Observation frequency, 23 kMc. (From W. Gordy and H. Shields (8).) 



Fig. 10. Resonance (first derivative curve) of bovine albumin which represents a 



combination pattern of the glycyl-glycine (or silk) doublet and cysteine (or hair) 



resonance. Observed at 23 kMc. (From W. Gordy and H. Shields (8).)
