Novel 2D and 3D pulse sequences producing images through the phase encoding of intermolecular multiple quantum coherences (i-MQCs) are presented. The signal acquired with these sequences is free from intermolecular zero quantum coherences (i-ZQCs) which are not phase encoded and additional phase cyc
The behavior of intermolecular multiple-quantum coherences in a variety of simple liquids with different chemical and magnetic properties is investigated experimentally and modeled by numerical simulations based on modified Bloch equations. The effects of spin concentration, temperature, intramolecu
## Abstract Resolution enhancement in NMR spectra, acquired in spatially or temporally varying magnetic fields, can be achieved with 2D pulse sequences detecting intermolecular zeroβquantum coherences (iZQC). The insensitivity towards long range field distortions renders these methods particularly
