This magnetic field makes the possible spin-states of the nucleus differ in energy, and using NMR techniques the spins can be made to create observable transitions between the spin states. Common NMR active nuclei are 1H, 13C, 31P, 15N, 29Si, and many more.wo-dimensional NMR spectra have two frequency axes, which can correspond to like nuclei (i.e. 1H-1H) or different nuclei (i.e. 1H-13C), and a third dimension of peak intensity. More recently, NMR experiments have been developed that contain information in three, four, and even five dimensions.
Resonance Raman (RR) spectroscopy is a name given to Raman spectroscopy when the incident laser frequency is close in energy to an electronic transition of a compound or crystal under examination.n resonance Raman spectroscopy, the energy of the incoming laser is adjusted such that it or the scattered light coincide with an electronic transition of the molecule or crystal. In most materials the incoming and outgoing electronic resonances are sufficiently broad that they can not be distinguished.
