Constant-time method for measuring inter-nuclear distances in static powders.
We present a constant-time modification of a single-echo 2D technique for measuring the constants of spin-spin interaction between heteronuclei in static powder samples. Compared to the sequence with variable echo time, the new scheme provides higher resolution. Another important improvement is a possibility to eliminate the central peak from a natural-abundance matrix. The experimental results are presented for glycine-[13Calpha, 15N] and glycine-[13C', 15N].
