Electron paramagnetic resonance

Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a technique for studying materials with unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but it is electron spins that are excited instead of the spins of atomic nuclei. EPR spectroscopy is particularly useful for studying metal complexes or organic radicals. EPR was first observed in Kazan State University by Soviet physicist Yevgeny Zavoisky in 1944, and was developed independently at the same time by Brebis Bleaney at the University of Oxford.

Theory

Origin of an EPR signal

Every electron has a magnetic moment and spin quantum number , with magnetic components and . In the presence of an external magnetic field with strength , the electron's magnetic moment aligns itself either parallel () or antiparallel () to the field, each alignment having a specific energy due to the Zeeman effect:

where

Magnetic resonance (quantum mechanics)

Magnetic resonance is a phenomenon that affects a Magnetic dipole when placed in a uniform static magnetic field. Its energy is split into a finite number of energy levels, depending on the value of quantum number of angular momentum. This is similar to energy quantization for atoms, say e− in H atom; in this case the atom, in interaction to an external electric field, transitions between different energy levels by absorbing or emitting photons. Similarly if a magnetic dipole is perturbed with electromagnetic field of proper frequency(), it can transit between its energy eigenstates, but as the separation between energy eigenvalues is small, the frequency of the photon will be the microwave or radio frequency range. If the dipole is tickled with a field of another frequency, it is unlikely to transition. This phenomenon is similar to that, when a system is acted on by a periodic force of frequency equal to its natural frequency.

  How does an MRI work? | MRI basics explained | Animation

  What is an MRI and how does it work? This video contains an animated, visual explanation of the basic principles of an MRI. Magnetic resonance imaging (MRI) is a test that uses powerful magnets, radio waves, and a computer to make detailed pictures of the inside of your body. Your doctor can use this test to diagnose you or to see how well you've responded to treatment. Unlike X-rays and computed tomography (CT) scans, MRIs don’t use the damaging ionizing radiation of X-rays.

  This is an excerpt from the Visible Proofs exhibit. Visible Proofs depicted the history of forensic medicine, and how over the centuries, physicians, surgeons, and other professionals struggled to develop scientific methods that translated views of bodies and body parts into “visible proofs” that judges, juries, and the public could accept as valid.

What is an MRI and how does it work? This video contains an animated, visual explanation of the basic principles of an MRI. Magnetic resonance imaging (MRI) is a test that uses powerful magnets, radio waves, and a computer to make detailed pictures of the inside of your body. Your doctor can use this test to diagnose you or to see how well you've responded to treatment. Unlike X-rays and computed tomography (CT) scans, MRIs don’t use the damaging ionizing radiation of X-rays.

What is an MRI and how does it work? This video contains an animated, visual explanation of the basic principles of an MRI. Magnetic resonance imaging (MRI) is a test that uses powerful magnets, radio waves, and a computer to make detailed pictures of the inside of your body. Your doctor can use this test to diagnose you or to see how well you've responded to treatment. Unlike X-rays and computed tomography (CT) scans, MRIs don’t use the damaging ionizing radiation of X-rays.

This is an excerpt from the Visible Proofs exhibit. Visible Proofs depicted the history of forensic medicine, and how over the centuries, physicians, surgeons, and other professionals struggled to develop scientific methods that translated views of bodies and body parts into “visible proofs” that judges, juries, and the public could accept as valid.

I've spent the last few months collating past papers from multiple different countries selecting the most commonly asked questions. You'll be surprised how often questions repeat themselves! The types of questions asked in FRCR, RANZCR AIT, ARRT, FC Rad Diag (SA), ABR qualifying Core Physics and MICR part 1 are surprisingly similar and the key concepts remain the same throughout. I've taken the most high-yield questions and answered them in video format so that I can take you through why certain answers are correct and others are not. Happy studying, Michael #radiology #radres #FOAMrad #FOAMed

Electron paramagnetic resonance

Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a technique for studying materials with unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but it is electron spins that are excited instead of the spins of atomic nuclei. EPR spectroscopy is particularly useful for studying metal complexes or organic radicals. EPR was first observed in Kazan State University by Soviet physicist Yevgeny Zavoisky in 1944, and was developed independently at the same time by Brebis Bleaney at the University of Oxford.

Theory

Origin of an EPR signal

Every electron has a magnetic moment and spin quantum number , with magnetic components and . In the presence of an external magnetic field with strength , the electron's magnetic moment aligns itself either parallel () or antiparallel () to the field, each alignment having a specific energy due to the Zeeman effect:

is the electron's so-called g-factor (see also the Landé g-factor), for the free electron,
