True enough after he eyeballs the images of nuclear magnetic spectra.
FIG. 4. 1D 1H NMR spectra of A12-b (A) and B12-b (B). Anomeric and other structural reporter proton resonances are indicated by roman numerals corresponding to the position of the residue in the sequence as shown in the formulae.
That image was from Inhibition of Adhesion of Plasmodium falciparum-Infected Erythrocytes by Structurally Defined Hyaluronic Acid Dodecasaccharides
And I would say that "spectra" are not images. MRI produces an "image" in the same sense as a camera does--a geometric representation of a physical object---a spectrometer doesn't.
