I have a feeling that the spectrscopy problems in my course are a little on the tougher end. They typically involve NMR (usually 1H, 13C, or both), IR, as well as some clues about the molecule's reactivity. E.g. in this question, we are given the hint that a polymer was reacted...
In practice, the weak-readout-gradient approach has been little used in spatial encoding methods. 4. Spatial encoding of NMR interactions 4.1. Ultrafast 2D NMR Much of the power of NMR spectroscopy comes from the possibility to record multidimensional (ND) information, which not only provides ...

Research has shown that Kuru disease has been eradicated, where it acquired through consumption of the brains of infected humans killed by the disease during the practice of funerary cannibalism [176]. FFI is an autosomal illness characterized by lesions in the thalamus of the brain. GSS is ...
Not only that, the conductive gel used by ECG electrodes may cause allergic reactions in users, and non-medical ECG electrodes are prone to problems, such as displacement or detachment. Most importantly, ECG technology is not suitable for specific populations, such as infants and large-area burn...
