✦ Synopsis
By means of the classical transverse continuous wave nuclear magnetic resonance (NMR) the forbidden transitions at double Larmor frequency for hydrogen tlave been observed. The NMR spectra have been measured directly by scanning the external magnetic field up to 10 mT at temperatures about 30 mK. The intensity of the forbidden transition at double Larmor frequency 1 2 is of the same order of magni tude as the intensity I of ttle main Larmor line under these condItions. The intensity ratio I, II? depends on ttle external magnetic field in accordance with Cheng theory and NMR-SQUID measurements of Kohl and coworkers.
