Figure 2. Spectra acquired from the Intralipid phantom with increasing t₁ in the 1D ge-HMQC (heteronuclear multiple quantum coherence) and the 1D ge-HSQC (heteronuclear single quantum coherence).

(A and B) In A, the results for the 1D ge-HMQC are shown, while in B, the outcome of the 1D ge-HSQC sequence is presented. The evolution time (t₁) was increased with 1 ms every step and started at, respectively, 7.6 and 4.2 ms. It is apparent that the signal acquired with the ge-HMQC decays rapidly with an increasing t₁.
