DEER-Stitch: Combining three- and four-pulse DEER measurements for high sensitivity, deadtime free data

► 2p Primary echo in EPR is more intense than 3p refocused echo. ► The echo difference adversely effects 4p DEER compared to 3p DEER. ► 3p and 4p DEER time traces can be combined to give a good-signal-to-noise ratio deadtime free DEERS signal. ► DEERS applied to measure a nanowire, long distances and Cu-Cu coupling.
