Homework Statement
To find the spin-lattice relaxation time (), I could use the below equation to get my value.



For the spin-spin relaxation time, however, is there a similar equation I could use as well to find for (i.e. the spin-spin relaxation time)?
Relevant Equations
The below equation may (or may not) come in handy.




Note that is the intensity of the echo.
Please refer to the homework statement.

Or, if one would like to put it in other words, how would I go about finding if I know the delay time between 90-degree and 180-degree pulses? Is there an equation that helps solve this succinctly?

can you define "delay time between 90-degree and 180-degree pulses" for a person who doesn't know nmr? what experiment does that describe? The question boils down to what values can you plug in for , and .

The is given using the equation
