In an APT experiment the delay has to be set to a compromise value based on the average value of a one bond C H coupling Suppose that we take this value to be 130 Hz, what will be the value for the delay The one bond C H coupling in an ethyne (acetylene) group C C H can be as large as 250 Hz In an APT spectrum with T set to the value you have computed, how would the line from such a carbon be affected Does the line appear with the expected sign

Question: In an APT experiment the delay has to be set to a compromise value based on the average value of a one-bond C-H coupling.

In an APT experiment the delay τ has to be set to a compromise value based on the average value of a one-bond C-H coupling. Suppose that we take this value to be 130 Hz, what will be the value for the delay τ? The one-bond C-H coupling in an ethyne (acetylene) group -C=C-H can be as large as 250 Hz. In an APT spectrum with T set to the value you have computed, how would the line from such a carbon be affected? Does the line appear with the expected sign?
