The trans-isomer of oxyhydroxymethyl is
the lower energy form. Transitions with small
quantum numbers were reported by
(1) T. Oyama, W. Funato, Y. Sumiyoshi,
and Y. Endo,
2011, J. Chem. Phys. 134, 174303.
Field-free transitions with larger quantum
numbers in the upper millimeter region were
published by
(2) H. E. Radford, W. Wei, and T. J. Sears,
1992, J. Chem. Phys. 97, 3989.
Two assignment errors in (2) were corrected
in
(3) T. J. Sears, H. E. Radford, and M. A. Moore,
1993, J. Chem. Phys. 98, 6624.
One 1 MHz typographical error in (2) was
corrected here. In addition, one hyperfine component
from (1) was omitted because of large residuals.
The predictions should be sufficiently accurate
for the detection of the molecule in the cold ISM.
Otherwise, a-type transitions as well as
b-type transitions with Ka =
1 – 0 should be viewed with caution
if the predicted uncertainties exceed 0.5 MHz.
Other b-type transitions should be viewed
with some to great caution throughout.
The ab initio dipole moment was reported
in (1).
