Oxythiohydroxymethylium is considerably lower in
energy than its thioxyhydroxymethylium isomer
according to ab initio calculations. With respect
to the first entry from Sep. 2011, extensive
millimeter and submillimeter data were reported
by
(1) V. Lattanzi, S. Spezzano, J. C. Laas, J. Chantzos,
L. Bizzocchi, K. L. K. Lee, M. C. McCarthy, and P. Caselli,
2018, Astron. Astrophys. 620, Art. No. A184.
Three low frequency transitions were reported
by
(2) M. C. McCarthy and P. Thaddeus,
2007, J. Chem. Phys. 127, Art. No. 221104.
The parameter set is slightly different from that in (1).
Calculations should be sufficiently accurate for all
observational purposes. They should be viewed with caution
for a-type transitions with
Ka = 5 and higher, for
b-type transitions with
Ka = 2 – 1 and higher,
or for transitions with calculated uncertainties of more
than 0.2 MHz.
The dipole moment components are from an ab initio
calculation by

2006, J. Chem. Phys. 124, Art. No. 044322.
