The document is a table of NMR frequencies, listing the natural abundance, relative sensitivity, and absolute sensitivity of different isotopes. The data in the table can help researchers understand the NMR frequency characteristics of different isotopes at different magnetic field strengths.
This document provides a comprehensive table titled 'The Table of NMR Frequencies (By Mass)'. It lists data for numerous chemical elements and their specific isotopes. The entries include the isotope name, nuclear spin value, natural relative abundance percentage, absolute frequency values at multiple magnetic field strengths (ranging from 2.357T to 21.147T), and sensitivity factors.
The table provides NMR frequencies for magnetic field strengths ranging from 2.357 T to 21.147 T.
