Diamond is diamagnetic. Small defects in the diamond lattice can be paramagnetic, and if you search for "paramagnetic diamond" you'll find all sorts of links to scientific papers on the phenomenon. The unpaired electron gives it the property of paramagnetism.

2- The presence of unpaired electron in the molecule indicates that it is paramagnetic molecule. The stability of the ion as well as its paramagnetic character has been confirmed experimentally. The bond length of H 2
Paramagnetism is a consequence of having one or more un-paired electrons in the outer electronic configuration. e.g. O$_2$, and NO. Whether a molecule is paramagnetic or not is only explained using molecular orbital theory. In the case of O$_2$ it is found that the lowest energy state is one that...

Bond order is the number of chemical bonds between a pair of atoms; in diatomic nitrogen (N≡N) for example, the bond order is 3, while in acetylene (H−C≡C−H), the bond order between the two carbon atoms is 3 and the C−H bond order is 1.

Introduction to Molecular Orbital Theory
Kita juga dapat menentukan molekul tersebut bersifat paramagnetic atau diamagnetic. Jika semua elektron telah berpasangan maka molekul tersebut bersifat diamagnetic. Jika salah satu atau lebih elektron belum berpasangan maka molekul tersebut bersiafat paramagnetic.
total valence electrons. Will the molecule or ion be diamagnetic or paramagnetic? c. 13 d. 14 a. 10 b. 12 77. Use molecular orbital theory to predict whether or not each molecule or ion should exist in a relatively stable form. a. b. c. He2
Atoms or molecules in which the electrons are paired are diamagnetic repelled by both poles of a magnetic. Those that have one or more unpaired electrons are paramagnetic attracted to a magnetic field. Liquid oxygen is attracted to a magnetic field and can actually bridge the gap between the poles of a horseshoe magnet.

diamagnetic pairs of Co"I-NC-Fe" (Figure. 3-3 (a), C sites). Below Tc when the sample is exposed to the red-light, the charge transfer occurs between the Fe and Co ions within the diamagnetic pair (Figure. 3-3 (a), C sites). The electron from the Fe"I ion transfers to CoIII ion and the diamagnetic pair becomes a photoinduced magnetic FeII-CN ...
It has a bond order of 2.5 and is a paramagnetic molecule. The energy differences of the 2s orbitals are different enough that each produces its own non-bonding σ orbitals. Notice this is a good example of making the ionized NO + stabilize the bond and generate a triple bond, also changing the magnetic property to diamagnetic.

2. VB Theory shows O2 as sp2 hybridized with one s bond and one p bond. There are two lone pairs on each O. O22- has one s bond, and each O has three lone pairs. MO Theory shows a bond order of 2 for O2 and that it is paramagnetic. MO Theory shows a bond order of 1 for O22- and diamagnetic. But MO Theory fits the real data that O2 is paramagnetic.
Paramagnetism. Quite the same Wikipedia. In contrast with this behavior, diamagnetic materials are repelled by magnetic fields and form induced magnetic fields in the direction opposite to that of the applied magnetic field.[1] Paramagnetic materials include most chemical elements and some...
From the result, you can say that: wavenumber for the O–H/D stretch to a higher value the ion is paramagnetic the ion has a bond order shifts the wavenumber for the O–H/D stretch to a lower of zero the ion is likely to be less stable than He2 value has no effect on the absorption due the ion is diamagnetic to n(O–H/D) dramatically alters ...
According to this structure, the molecules should be paramagnetic, but actually it is diamagnetic. According to Linnett theory, a set of 7 electrons of one spin and another set of 5 electrons of another spin are considered to have a tetrahedral orientation around the two oxygen atoms as shown in Fig. 3.81. x

If all the electrons are paired, the molecule is diamagnetic. If one or more electrons are unpaired, the molecule is paramagnetic. • The bond order is 1. Bond Order = 1/2(2 - 0) = 1 • The bond order above zero suggests that H2 is stable. • Because there are no unpaired electrons, H2 is diamagnetic.
Atoms or molecules in which the electrons are paired are diamagnetic repelled by both poles of a magnetic. Those that have one or more unpaired electrons are paramagnetic attracted to a magnetic field. Liquid oxygen is attracted to a magnetic field and can actually bridge the gap between the poles of a horseshoe magnet.

Jan 01, 1996 · When the diamagnetic shift is obtained from a diamagnetic analog of the paramagnetic metalloprotein under study (e.g., in a different oxidation state (Banci et al., 1996a)), one may use a smaller tolerance. For example, in Banci et al., 1996a, a tolerance of 0.05 ppm was used.
