NMR Spec...Help

For Hydrogen/Proton NMR, if a hydrogen is within three bonds of an more electronegative element (e.g Oxygen) then it will have a higher chemical shift value. (further left)

ohhh my i'm so confused :/

shouldnt it have a lower chemical shift value cause less magnetic field engergy is required to flip it?

The NMR shift scale goes from right to left, not left to right.

Be careful. Yeah, chemists are stupid, I don't know why the scale is that way.

thank you so much! I really appreciate it..so basically
so the chemical shift values is the measure of magnetic field strength and molecules that are shielded have a lower chemical shift value cause the nucleus isn’t feeling the strength of the mag field...and molecules that are de-shielded have a higher value cause they're absorbing the energy more. Is this right?

The chemical shift value is really just an amount in Hertz...an amount of energy.

That amount of energy is really just the difference between two energy levels

Amount of energy = energy level 1 - energy level 2


Of course, the difference between those two energy levels (and therefore the amount of energy) depends on the magnetic field, how? Well, a bigger field increases the gap between the two levels...

Or, you can remove electrons from the nucleus with electronegative elements, deshielding it, this means that the nucleus 'feels' a bigger magnetic field....it seems as if there is a larger magnetic field...you understand?

Yeahh i do, so if a molecule is sheilded it will show up at the far left of the spectra with a higher chemical shift value yeah?becuase of the reasons you mentioned right? thankyou!

...

The graph goes from right to left. Increasing energy as you go from right to left.

If a molecule is shielded it will show up on the far right with a lower chemical shift value because it feels a smaller magnetic field...
