NMR sample tubes. Rack of tubes containing samples for analysis by nuclear magnetic resonance (NMR) spectroscopy. This technique uses radio waves to provoke hydrogen atoms to emit signals. The type of signal depends on the atoms surrounding them in the molecule. By studying the pattern of the signals, a structure for the molecule can be determined. NMR is used extensively in organic synthesis.
