英文摘要	NNSF of China [10774125, 10875101]; Chinese Ministry of Education [109092]; National Key Technology R&D Program of China [2006BAK03A22]; A new pulse sequence based on intermolecular single-quantum coherences (iSQCs) is proposed to obtain high-resolution NMR spectroscopy in inhomogeneous magnetic fields via fast 2D acquisition Taking the intrinsic properties of iSQCs. the sequence is time-efficient with a narrow spectral width in the indirect dimension It can recover useful information of chemical shifts, relative peak areas, J Coupling constants, and multiplet patterns even when the field inhomogeneity is severe enough to erase almost all spectroscopic information Moreover, good solvent suppression efficiency can be achieved by this sequence even with imperfect radio-frequency pulse flip angles Spatially localized iSQC spectroscopy was performed on a sample packed with pig brain tissue and cucumber to show the feasibility of the sequence in in vivo magnetic resonance spectroscopy (MRS) This sequence may provide a promising way for the applications on in vivo and in situ high-resolution NMR spectroscopy (C) 2009 Elsevier Inc All rights reserved
