Abstract
For pseudoscalar meson electroproduction off the nucleon in parallel kinema tics a relation between three polarization observables is derived. It is sh own that, without Rosenbluth separation, a measurement of the longitudinal strength can be achieved through three different ways. They are discussed w ith preliminary MAMI data for the p((e) over right arrow, e'(p) over right arrow)pi(0) reaction in the energy range of the Delta(1232) resonance.
