Abstract
After reviewing the basic principles of zero-field NMR spectroscopy at high magnetic fields (ZFHF NMR) as introduced by Robert Tycko, a 2-di mensional extension of this method is described which enhances its sen sitivity by at least one order of magnitude. The essential point is a combination of the original pulse program including sample rotation wi th a Carr-Purcell pulse sequence during the acquisition time. Experime ntal results are given for the proton resonance of meta-C6H2D4 dissolv ed in C6D6 at 245 K.
