In this context, ethynyl derivatives of naphthalene are promising candidates to be observed in the Taurus Molecular Cloud (TMC-1), where cyanonaphthalenes together with cyano- and ethynyl- derivatives of cyclopentadiene and benzene have been detected. To enable the interstellar searches for ethynyl derivatives of naphthalene, their pure rotational spectra need to be investigated in the laboratory. We have observed for the first time the rotational spectra of 1- and 2-ethynylnaphthalene species using a broadband Fourier-transform microwave spectrometer operating in the 2-8 GHz frequency region. Accurate spectroscopic parameters are derived from the analysis of the experimental spectra, allowing for reliable predictions for astronomical searches. Our searches in TMC-1 for both isomers provide upper limits for the abundances of these species.CC and JC thank European Research Council for funding support under Synergy Grant ERC-2013-SyG, GA 610256 (NANOCOSMOS) and Ministerio de Ciencia e Innovacion´ through the PID2019-107115GB-C21 project.
