N1 - Funding Information: We are indebted to Professor R Berger for providing us with the code hotFCHT for calculations of FC factors in polyatomic molecules. TI is especially grateful to R Berger for numerous insightful discussions during joint work on the calculations of -oddand ,  -oddproperties for molecules with open electronic shells and implementing the routines for the calculation of these properties within the tm2c code. We thank Dr Yu V Lomachuk and Dr Yu A Demidov for technical help. Financial support from RFBR (Grant Nos. 16-02-01064 and 16-03-00766) and computer time provided by the Center for Scientific Computing (CSC) Frankfurt, is gratefully acknowledged.

N2 - Recently, a few diatomic and polyatomic molecules have been identified as prospective systems for Doppler/Sisyphus cooling. Doppler/Sisyphus cooling allows us to decrease the kinetic energy of molecules down to μK temperatures with high efficiency and allows their capture in molecular traps, including magneto-optical traps. Trapped molecules can be used for creating molecular fountains and/or performing controlled chemical reactions, high-precision spectra measurements, and a wealth of other applications. Polyatomic molecules with heavy nuclei are of considerable interest for the 'new physics' search outside of the Standard Model and other applications including cold chemistry and photochemistry, quantum informatics, etc. Here, we focus on the radium monohydroxide molecule (RaOH), which is on the one hand amenable to laser cooling and on the other hand opens excellent possibilities for -odd and -odd effects research. At present, RaOH is the heaviest polyatomic molecule proposed for direct cooling with lasers.
