Chromium acetylacetonate is often added to speed up this specific technique. The INADEQUATE form of this specific technique can only be performed at high concentrations. The results from this technique are plotted on the axis with a larger range in HMBC or HMQC experiments. One form of this technique produces positive peaks at 45 and 90 degrees and either positive or negative peaks at 135 degrees. That form of this technique improves sensitivity with polarization transfer and is called DEPT. Perfect broadband decoupling in this technique gives a signal enhancement of up to 1.99 via the NOE, which is useful since this technique must overcome a small gyromagnetic ratio. This technique produces a cluster of background peaks at77 ppm due to deuterated chloroform. For 10 points, name this technique which measures energy absorption by nuclei with atomic mass 13.
