We present here the FTMW spectra of the various isotopologues of the intermediate strength bound complex of dihydrogen with copper fluoride.\footnoteD. J. Frohman, G. S. Grubbs II, Z. Yu, S. E. Novick, Inorg. Chem. , \textbf52, 816-822 (2013). The bond between the two moieties is surprisingly strong, the H--H forming the cross of the T with the Cu closest to H2 in the C_\mathrm2v structure. Laser ablation was used to produce both copper isotopologues of p -H2--CuF, o -D2--CuF, and HD--CuF whose J = 1 - 0 transitions were observed. Significant changes in the nuclear quadrupole coupling constants for the copper nucleus in H2--CuF compared to that in uncomplexed CuF suggests bonding greater than that typical of van der Waals interactions. This talk will serve as the introduction to presentations at this meeting of other H2 metal containing diatomics.
