We got a report that a DEPT135 spectrum did not look good. I confirmed this observation using my favorite sample, 3-heptanone in CDCl3. When a DEPT looks bad it is usually incorrect pulse widths. Sarah recalibrated 1H and 13C pulse widths and now the DEPT looks great. Yeah Sarah!
One problem - why is the 1H pulse width so far off? The probe tuning is and and we cannot tune the 1H channel properly. It seems that at some point we have fried the probe and will have to send it away for repair. It will be a major priority to discover how we did this damage!
