\item IIIZw 35 -- pc-size OH clouds of edge-on torus (pihlstrom+01) - has diffuse and compact components in ring structure amplifying bkg continuum (parra+05)  \item Arp 299 appears to show OH emission from the nucleus of IC 694 (baan 85); H2O MM emission as well (tarchi+07a) slight offset from OH in a nuclear outflow (Tarchi+11a)  \item 5 other galaxies show masers in both, but are not MMs (includes NGC 253 and M82, nearby starbursts, Tarchi+11a)  \item Why the mutual exclusion?? wiggins+15 searches for 22 Ghz emission in OH MM galaxies w/ GBT -- second detection in IIZw96, also a merger  \item sample from tarchi+10 of OH emitters visible at GBT that had never been searched for 22 GHz emission -- 47 objects observed  \item IIZw 96 shows high luminosity, narrow features in water; no high velocity shifts so not associated w/ a disk  -- close resemblance to Arp 299 water line; features consistent with pumping from the AGN  \item suggestive of a brief phase in galaxy mergers where maser coexistance is possible  \item evidence also possibly shows exclusion for kilo-masers in OH MM hosts  \item tentative detection of IRAS 15179+3956, another merging system  \end{itemize}
