⁷Li and ¹H-NMR measurements were carried out for a layered superconductor Li_0.48(THF)_yHfNCl which shows superconductivity at T_c approx. 23.5 K. We report the characteristic superconducting parameters such as, the penetration depth (λ), the coherence length (ξ), lower critical field (H_c1), and upper critical field (H_c2). From ⁷Li-NMR studies, it is suggested that the Fermi level density of states at the intermediate Li site are considerably small and the superconductivity is derived from the HfNCl layer.
