EPR spectrum measured by FT of the chirped echo

An EPR spectrum of 100 G (280 MHz) width was measured by FT of the chirped echo. In this way measuring time is reduced drastically by the multiplex advantage. There is some amplitude reduction of the outer lines due to receiver bandwidth limitation but the achieved excitation bandwith can not be obtained by a single frequency pulse.
