Rotational transitions of the \textit{p}-H$2$-CuCl and \textit{o}-H$2$-CuCl have been observed on a laser ablation equipped FTMW cavity instrument. Computational studies preformed using the APFD \textbf{8} (2012) 4989.} density functional and MP2 level of theory were used to predict the structure of the \textit{p}-H$2$-CuCl. Measurements from the J=1--0 to the J=3--2 transitions were used to determine the rotational constants, centrifugal distortion constants, and quadrupole coupling constants for multiple isotopologues of the \textit{p}-H$2$-CuCl species. Similar constants, including spin-spin coupling constants, have also been determined for the \textit{o}-H$2$-CuCl species for the J=2--1 and the J=3--2 transitions.
