How many tesla are used in a 600 mhz nmr
WebA single conversion may not be a great inconvenience but it must be done for every peak for each system. Now consider the same signal but quoted in the ppm unit. Frequency in Hertz divided by SFO1 = Frequency in ppm. Examples: 2500 Hz / 500 MHz = 5 ppm. 3000 Hz / 600 MHz = 5 ppm. 2000 Hz / 400 MHz = 5 ppm. Webrange 14000-140000 Gauss (1.4-14 Tesla). •A proton in the ground state will absorb radiation having a frequency of ca 60 mHz at 1.4 T and ca 600 mHz at 14 T. •NMR instruments are described in terms of the frequency at which they cause protons to resonate; thus a 600 mHz instrument is one
