(a) 2D 3QMAS spectra of solvated Alq
(containing ethanol). Optimised excitation and conversion pulse lengths were 4.6 μs and 2.5 μs. A total of 192 t1 increments was taken with 8 μs of dwell time with 96 transients per increment. The recycling dealy was 1 s. Total experiment time was 5 hours 18 mins. (b) The anisotropic slice along the direction parallel to the F2 dimension. (c) The isotropic projection along the F1 dimension.
