(a.) Pertaining to, or exhibiting the phenomena of, diamagnetism; taking, or being of a nature to take, a position at right angles to the lines of magnetic force. See Paramagnetic.
(n.) Any substance, as bismuth, glass, phosphorous, etc., which in a field of magnetic force is differently affected from the ordinary magnetic bodies, as iron; that is, which tends to take a position at right angles to the lines of magnetic force, and is repelled by either pole of the magnet.
Example Sentences:
(1) The Soret MCD of the reduced protein is interpreted as th sum of two MCD curves: an intense, asymmetric MCD band very similar to that exhibited by deoxymyoglobin which we assign to paramagnetic high spin cytochrome a3(2+) and a weaker, more symmetric MCD contribution, which is attributed to diamagnetic low spin cytochrome a2+.
(2) These results suggested that most of the cytochrome d under the air-oxidized conditions contains a diamagnetic iron atom with a bound dioxygen.
(3) A substantial shortening of the T1 for Tl+ bound to either protein was observed in the presence of Mn2+, an effect not noted upon substitution of Mn2+ with the diamagnetic cation Ca2+, which is known to bind to these proteins in a similar fashion to Mn2+.
(4) Proton NMR experiments of tetracycline, spin-labeled tetracycline, and the diamagnetic reduced form in DMSO-d6 are reported.
(5) Magnetic anisotropy in proteins and polypeptides can be attributed to the diamagnetic anisotropy of the planar peptide bonds.

(13) It would follow that if mitoxantrone does not redox cycle in the presence of reductases, then the semiquinone free radical is not produced or, if it is formed, it reacts quickly to form diamagnetic products.
(14) The diamagnetic (S = 0) state MOX is attained by oxidation of the native state MN with either thionine or oxygen.
(15) The 1H-NMR spectrum of the aerobically isolated protein is reported at 300 MHz; magnetic susceptibility measurements were indicative of a diamagnetic species.
(16) This combination of techniques allows charge-transfer spectral features associated with N-3 binding to the paramagnetic type 2 Cu(II) to be differentiated from those associated with binding to the antiferromagnetically coupled, and therefore diamagnetic, binuclear type 3 Cu(II) site.
(17) Complexes of ATP with paramagnetic ions such as Co2+ and Mn2+ were less inhibitory than complexes with diamagnetic ions, including Ca2+ and Mg2+.
(18) The apoferritin results are in every way typical of diamagnetic spherical proteins of their size (K. Hallenga and S. H. Koenig, Biochemistry 15, 4255 (1976)).

Definition:
(n.) The science which treats of diamagnetic phenomena, and of the properties of diamagnetic bodies.
(n.) That form or condition of magnetic action which characterizes diamagnetics.
