[Question from NMRWiki Q&A forum] NMR transmission, polarized magnetic field and rotation along x' and y' axis

NMR transmission, polarized magnetic field and rotation along x' and y' axis

I am trying to understand the workings of the NMR transmission more closely. I understand how the sinusoidally varying magnetic field created by the coil is used to tip the protons by 90deg.

I am having hard time understanding however, how using the phase shifted versions of the transmitted wave, one could achieve a 90(x') versus. 90(y') "tipping" of the protons?

Another question I have is why is circularly polarized magnetic field is required for this?

I have RF background, but I am new to the NMR community, and trying to fill the gap between how RF works and how it is used for the purpose of NMR.

I appreciate any help in answering these questions, or even if someone points me to a textbook or research article that explains this...

Thank you.
