对抹香鲸高铁肌红蛋白的7个H-2组氨酸核磁共振峰和羰基肌红蛋白及氧合肌红蛋白的11个H-2组氨酸核磁共振峰进行了归属，并测定了它们的pK′值;表面组氨酸有六条滴定曲线，它们在三种衍生物中相似，另外三条在羰基和氧代衍生物中相似，而另一个（远端组氨酸）在前者中具有低pK′，在后者衍生物中具有正常pK′。
Seven H-2 histidine n.m.r.resonances of sperm whale metmyoglobin and eleven resonances of both carbonyl- and oxy-myoglobin are assigned and pK′ values determined; there are six titration curves from surface histidines which are similar in the three derivatives, three others which are similar in the carbonyl and oxy derivatives, and one other (the distal histidine) which has a low pK′ in the former and a normal pK′ in the latter derivative.
