NMR multiple-quantum dynamics with various initial conditions

An approach to creating the highest-order multiple-quantum coherences is developed. The method is based on using the multiple-quantum NMR technique and various initial conditions and can be considered as supplemental to earlier developed methods. Using the dipolar ordered state as the initial one, it is demonstrated that in a cluster of four and eight dipolar-coupled nuclear spins the highest-order multiple-quantum coherences can be created.
