Both disks show rich molecular emission, including H$_2$O, CO$_2$, HCN, C$_2$H$_2$, and OH. The scaled spectra of the two disks exhibit remarkably similar H$_2$O, CO$_2$, and HCN line emission in the 13-18 $\\mu$m region, with the only notable difference being stronger C$_2$H$_2$ emission in the primary (Sz 65).
