We report spectroscopy near 2.2 $\mu$m of several luminous (L$_{IR}$ = 10$^{11}$ - 10$^{12}$ L$_{\odot}$) infrared galaxies. The spectra were obtained using CGS4 on the United Kingdom Infrared Telescope and CSHELL on the NASA Infrared Telescope Facility, and have resolving powers $\lambda / \Delta \lambda$ ranging from 330 to several thousand. Our sample includes starburst galaxies such as NGC 6240 and AGN such as NGC 1068. We show a preliminary rotation curve, obtained with CSHELL, for the luminous (L$_{IR}$ = 5.5 x 10$^{11}$ L$_{\odot}$) galaxy IRAS 1829 -34. Finally, we will discuss the H$_{2}$ v=1-0S(1) and Brackett $\gamma$ emission line strengths of these galaxies and compare these luminous objects to the ultraluminous objects (L$_{IR}$ $>$ 10$^{12}$ L$_{\odot}$) observed by Goldader et al. (ApJ, submitted).
