We propose a search for water, ammonia, formaldehyde, OH and methanimine in three gravitationally lensed, high-redshift Sub-Millimeter Galaxies (SMGs) as a pilot pro ject for a large scale study of molecular ISM in SMGs. High-z water masers have only been discovered in lensed systems, with the highest redshift being in a source at z=2.64. Having further detections of water in early universe would constrain the evolution of the H2 O maser sources' luminosity function throughout cosmic time. Detection of other molecules in these dusty, star-forming galaxies will pave the way for detailed studies of galactic chemistry at the epoch of the highest rate of star formation.
