Stochastic Nmr Spectroscopy

Among the different forms of spectroscopy, nuclear magnetic resonance (NMR) shows an intimate connection between theory and experiment. NMR therefore enjoys great popularity in the development of new methods. Following the rapid development in electronic and computer technology, NMR techniques evolved from singlechannel to multi-channel and multi-dimensional modes. The original continuous wave (CW) method (1-3) was extended to two dimensions with the introduction of double resonance (4-6). The CW techniques were replaced by corresponding multi-channel methods because of signal-to-noise improvements resulting from broadband excitation. The routine NMR methods are now one-dimensional (ID) (7,8) and too-dimensional (2D) (9-13) Fourier transform (FT) spectroscopy. The excitation energy is focused into a few pulses per experiment and the spectrum is computed from the experimental data by ID or 2D Fourier transformation. A conceptually more difficult method is
