| Abstract: | A new experiment is proposed for two-dimensional heteronuclear correlation spectroscopy. It involves the rapid creation of pure heteronuclear ZQC under cross-polarization, followed by an evolution period during which ZQC is converted to DQC. A read pulse is used to detect the signal. No phase cycling is required to determine the sign of ω1. |
