Organic Structures from 2D NMR Spectra
(2026) – Solutions Manual – Field
1H, 13C - answer-most common nuclei used in NMR
odd - answer-in order for nuclei to be analyzed by an NMR spectrometer, it must have an
________ number of nucleons
deshielded, shielded - answer-______ protons experience a net magnetic field strength that is
higher than the ______ protons
frequencies - answer-the strength of the magnetic field is a determining factor for the range of
______ that must be used for NMR spectrometer
signals - answer-the number _____ indicates the number of different kinds of protons
TMS - answer-used as a reference for recording NMR spectra and is assigned a chemical shift
value of zero
alpha - answer-the magnetic moment that aligns with the field, lower energy state
beta - answer-the magnetic moment that goes against the field, higher energy state
deuterated - answer-these types of solvents must be used for NMR
