      abstract     = {Aims. We investigate the outcome of an electrical discharge
                      of naphthalene and search for the resulting products in the
                      Taurus Molecular Cloud (TMC-1).Methods. Using chirped pulse
                      Fourier transform microwave spectroscopy paired with an
                      electric discharge source, we investigated products
                      resulting from the naphthalene discharge. Quantum chemical
                      calculations were used to help assign species and
                      investigate potential reaction pathways relevant to the
                      interstellar medium. These products were searched for in
                      TMC-1 using the QUIJOTE line survey, covering 31.0-50.3
                      GHz.Results. We confirm the detection of ethynylbenzene in
                      TMC-1, and we also present a new molecular species,
                      1,2-diethynylbenzene, which could play an important role in
                      the formation of naphthalene. Over ten products have been
                      identified as resulting from the discharge, with only one of
                      these species found in a previous IR-UV discharge study of
                      naphthalene.Conclusions. Ethynylbenzene has definitively
                      been detected in TMC-1, and while we have identified a
                      potentially important species for the formation of
                      naphthalene and an exothermic reaction pathway, there is no
                      current indication of its presence in TMC-1.},
