Superconductors based on transition metal dichalcogenides are of substantial current relevance, towards attaining topological superconductivity. Here we report a detailed study on the synthesis and electromagnetic characterization of high-quality single crystals of TaSeS. A superconducting transition is confirmed at 4.15K with coexisting charge density wave onset at 66K. The temperature dependence of RF penetration depth indicates s-wave characteristics in the weak coupling limit. A moderate electronic anisotropy is observed in upper critical fields with a value of 1.52. DFT calculations confirm the possibility of superconducting behavior of TaSeS and also suggest that the most stable structure belongs to P63mc space group. Negative values in phonon dispersion curves verify the possibility of co-existing CDW in 2H-TaSeS. Arrhenius plots show power law dependence of activation energy with respect to magnetic field. Overall all characteristics imply TaSeS to be a classic Type-II superconductor without any evidence for topological superconductivity.
