    "abstract": "For pseudoscalar meson electroproduction off the nucleon in parallel\nkinematics a relation between three polarization observables is derived. It is\nshown that, without Rosenbluth separation, a measurement of the longitudinal\nstrength can be achieved through three different ways. They are discussed with\npreliminary MAMI data for the p(\\vec e, e\u0027\\vec p)\\pi^0 reaction in the energy\nrange of the Delta(1232) resonance.",
