The measured lines were taken from E. F. Pearson and M. B. Trueblood, 1973,
Astrophys. J. Lett. Ed. {\bf 179}, L146, and P. Kuipers {\it et al.}, 1976, 
Chem. Phys.  {\bf 15}, 457.  Because no dipole moment measurement has been 
reported, we assumed a value of unity in our calculation.  Two theoretical 
estimates have been published:  N. G. Rambidi, Yu. G. Abashkin, and A. I. 
Dement'ev, 1984, Russ. J. Inorg. Chem. {\bf 29}, 12--22, and G. A. Long, 
J. F. Capitani, and L. Pedersen, 1983, J. Mol. Struct. {\bf 105}, 229--230.  
Of these, the Rambidi  {\it et al.} value is closer to our estimate of 6.63 
Debye with an estimated error of maybe 1 Debye, which is based upon 
extrapolations from the dipole moments of Li, Cs, and Na fluorides and the 
Cs and Li hydroxides.  The Rambidi  {\it et al.} value is 6.706 debye, while 
the Long  {\it et al.} value ranges between 6.30 and 5.42 debye, depending 
on the basis set used in their calculations.  The line intensities should 
be multiplied by a factor of about 44 to get something closer to the right 
value.  The theoretical calculations suggest that this molecule is linear.  
A measurement is needed.
