What is hmbc nmr

Which instrument should I use? This provides about 3x the amount of signal per scan compared to the autox probe, since it is optimized for 1H detect.

Signal-to-noise scales as the square root of the number of scans, so the 3x signal boost corresponds to about a 9x time savings. In other words, if you run a 9 hour HSQC overnight on the using the autox probe, you could obtain the same signal to noise ratio using the penta probe for 1 hour. You will see your 1H spectrum as your direct F2 axis and your 13C spectrum as your indirect F1 axis.

You will see a cross peak for any 1H connected to a 13C that is one bond away. Several betterments was proposed to increase sensivity, reduce artifacts like 1 J CH coupling , measure coupling constants, and others.
