2). These nuclei could not have been detected on the older continuous wave instruments, as the spectrum was the result of a single scan, obtained as one of the frequency or magnetic field were varied while keeping the other constan t . 2 Origin of the NMR Effect To explain the origin of the NMR effect, we have first to think about why something has a magnetic field associated with it. e. it moves in the presence of, or interacts with, other magnetic fields). The Earth has associated with it its own small but nonetheless significant magnetic field and a compass will interact with this and will always point North.
An F T experiment is carried out by placing the solution of the sample in a magnetic field and by irradiating it with a short pulse (broad spectrum) of radiofrequency radiation. The effect of this irradiation over such a broad range is that all the nuclei in the sample are excited at the same time. The NMR spectrometer then detects the radiation given off by the sample as the nuclei “relax” back to their lower energy state, and one way in which they can do this is by transferring energy to other, nearby, nuclei with spin (we will learn a little more about this later).
7) may be partly responsible (in addition to the C = C stretch) for the peak at 1620 cm-'. ' ~ '. 4 1500-1 000 cm-’? Fingerprint Region Absorptions in this region are largely due to the vibrations of the whole molecular skeleton, and this region is known as the “fingerprint region”. Because every organic molecule has absorptions in this region, i t is often difficult to pick out any functional group vibrations that happen to occur in this region, but there are a few which are sufficiently strong to stand out from the crowd of those belonging to the molecular skeleton.
