 The experimental frequencies were taken from 
D. Dangoisse, E. Willemot, and J. Bellet, 1978, J. Mol. Spect. {\bf 71},
414. 

	The total dipole moment was assumed to be the same as for the parent 
H$_2$CO, but the components are obtained by rotating the axes by an amount
which is calculated from the structure.
