Paramagnetism in coordination complexes
A complex is classified as paramagnetic or diamagnetic based on the electronic configuration of the central atom/ion. Should the properties (para/dia) of surrounding ligands also affect the nature of ...

Does a steel pestle corrode while pressing soot?
While experimenting with a few different powders, I noticed the resulting small flakes were ferromagnetic. Then I decided to find out what was the cause: after repeating the experiment with only soot, ...

Why does s and p orbitals dont contribute to para or ferromagnetism? [closed]
Like in metal Ag,contains unpaired electron in their s subshell and like Cl has unpaired electron in its p subshell,but they all show diamagnetism,what can be the reason for this?

Magnetic moment of an electron not parallel to its angular momentum?
For the total angular momentum of an electron $\vec{J} = \vec{L} + \vec{S}$, we're often shown a picture like this
where I assume that the $\vec{L}$ and $\vec{S}$ cones are centred on the $J$ axis ...

Why are fluorine-19 NMR spectra less affected by paramagnetic centers than other common nuclei?
I know that 19F NMR spectra are less sensitive to paramagnetic centers as an empirical fact: it’s my experience and that’s what people in my lab have always been saying.
For instance, some of my ...

Why are ions in a mass spectrometer accelerated through electric plates? [closed]
I was reading an article on the AP Chemistry course in Khan Academy about mass spectrometry, which had this:
... ions are then accelerated through electric plates and subsequently deflected by a ...

How are spin magnetic moment and orbital angular moment in opposition in a d3 ion in octahedral environment?
I have two queries firstly what does spin exactly mean and secondly how do i decide whether the spin and orbital moment are in opposition or not or is this an experimental fact.
I would also like to ...

Why are neodymium magnets called neodymium magnets?
Neodymium magnets have a formula of Nd2Fe14B, but why are they called neodymium magnets? There are more iron atoms, and iron makes up over half of the mass of a neodymium magnet. Why isn't it called ...

NMR spectroscopy nomenclature: induced vs local vs effective magnetic field (B)
This is a simple question but I can't seem to find a place where they use the same nomenclature... I was wondering whether these are all the same thing: $B_\mathrm{induced}$, $B_\mathrm{local}$, $B_\...

Why is octaoxygen diamagnetic?
I tried considering that according to LCAO-MO theory $\ce{O2}$ is paramagnetic, which is confirmed by experimental evidence. Since octaoxygen has the crystal structure in figure, I thought there is a ...

Do ferrofluid nanoparticles come out of solution when exposed to a solenoid DC field current?
As the electrically-charged ionic tails of surfactants used to attach to the magnetic nanoparticles require the particle to be magnetized to stick to them; if a ferrofluid is passed has a solenoid DC ...

Contribution, and the way thereof, of the core 6p orbitals of compounds of plutonium(VIII)
According to the NIST database, the ground-state configuration of plutonium(VIII) is [Hg]5f³6p³, when intuitively it should be the same as neutral radon([Hg]6p⁶). Since plutonium(VIII) compounds are ...

Why are most organic molecules diamagnetic, when most of them have non-paired nucleus spins?
I was studying some coordination chemistry and somewhere around the text it was stated that one could know the magnetic moment of a complex from its metal because since all ligands were often ...
