A NMR Experiment

  1. Apr 29, 2017 #1
    Hello
    I have to do an nmr experiement. Why do i need a broadband probe head? I have a magnet with 2 tesla. and modulation coils on it with a frequency of 50hz. For example i have a resonance frequency at 50mhz.
    i hope you can pelp me.

    You shouldn't need a broadband receiver, just a receiver near the Larmor frequency. Are you using the probe for multiple nuclei or field strengths?

    the idea is at resonance frequency the resistor is 50ohm. if something is into the probe head 50ohm it differs. and an nmr detector detects this and shows a signal.
    the problem is my prof says i need it and i dont want to ask him again because i didnt understand it.
    what can the reason be for a broadband signal? is the linewith always the same with this method?

    Um, that is part of your professor's job.

    Again, are you using the same receiver for multiple nuclei or field strengths?
