Could NMR be applied for other elements besides Hydrogen?

AI Thread Summary
Nuclear Magnetic Resonance (NMR) can indeed be applied to elements beyond hydrogen, including phosphorus and platinum, although hydrogen remains the most common focus. The primary challenge for multi-element scanning in NMR lies in the requirement for nonzero nuclear spin and the natural abundance of isotopes, as certain isotopes like 1H are much more prevalent than others like 13C. While it is feasible to conduct experiments with multiple elements, the varying natural abundances can complicate results. Isotopically enriched samples can help mitigate these issues, allowing for more effective multi-elemental mapping. Overall, NMR's versatility extends to various elements, but practical challenges must be addressed for comprehensive analysis.

Most books discribe NMR as a diagnotic technique for Hydrogen and its isotopes. Could Nuclear Magnetic Resonance Spectroscopy be applied for other elements with odd atomic number besides H? If so, what is the major challenge for a multi-element scanning?

It definitely can and it is not an uncommon practice. Here's an example of NMR using Pt:

Also note that electron spin resonance is a similar technique as NMR, but done onto the electron spin states.

Certainly. Phosphorous is a commonly used nucleus also.

Of four standard spectroscopic methods used in the organic analysis two are NMR techniques using different nuclei: H NMR and C-13 NMR. Two other are IR and MS.

Thank you so much for your answers guys! But what is the challenge to have a multi-elemental mapping using NMR, say, is it possible to have H, C13, P, etc.all elements with odd atomic numbers at the same time?

What NMR requires is a nonzero nuclear spin - for example, 2H and 14N are often used for (quadrupolar) NMR studies in a variety of applications.

You need to examine the natural abundance of each isotope to see how the numbers pan out - for example, 1H is the vastly predominant stable isotope (> 99.9%), 13C is the vastly non-dominant stable isotope (~ 1%), and 31P is the only stable isotope (100%). However, it is possible to produce isotopically enriched samples to make doing experiments easier in that regard. So a naturally occurring chemical/biological/material sample here on Earth will be extremely rich in 1H, all 31P, but have a small amount of 13C. This may or may not be a problem, depending on what you want to do.
 
The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...
Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
Thread 'Beam on an inclined plane'
Hello! I have a question regarding a beam on an inclined plane. I was considering a beam resting on two supports attached to an inclined plane. I was almost sure that the lower support must be more loaded. My imagination about this problem is shown in the picture below. Here is how I wrote the condition of equilibrium forces: $$ \begin{cases} F_{g\parallel}=F_{t1}+F_{t2}, \\ F_{g\perp}=F_{r1}+F_{r2} \end{cases}. $$ On the other hand...
