Fig. 5. 1H NMR diffusion-weighted spectra of the Val E11 signal of
MbO2 from seal muscle at 25°C: A modified pulse PGSTE sequence
detects the
CH3 Val E11 signal at –2.8 p.p.m. The
peak intensity decreases as gradient field strength increases in the
x direction: (a) 9.5 gauss cm–1 (1
gauss=104 tesla), (b) 23.8 gauss cm–1, (c) 47.5
gauss cm–1 and (d) 71.3 gauss cm–1.
