SQ-SQ Experiment for Determination of Relative Signs of Small nJ(29Si,13C) Couplings in a Wide Variety of Silicon Compounds
Original language description
A modification of DQ/ZQ experiment termed SQ-SQ experiment is proposed for determination of relative signs and magnitudes of coupling constants. The modification replaces the multiple quantum evolution period by two synchronously incremented single quantum periods. Similarly to DQ/ZQ experiment, the sequence requires only two coupling constants which share one nucleus, the one to be measured and a reference one. This allows application to a larger variety of molecular fragments than traditional 2D sequences producing E.COSY or TROSY pattern. The SQ-SQ experiment eliminates effects of some other couplings during t1 thus simplifying the 2D pattern and increasing signal intensity in comparison with DQ/ZQ experiment. The presented sequence is particularlydesigned for determination of silicon-carbon coupling constants across several bonds at natural abundance using silicon-hydrogen couplings as the sign reference.
