Vibrational fundamentals of glycolaldehyde 
up to 1500 cm-1 / 2150 K 
and vibrational correction factors to the partition function (at the bottom).

Qv is converged to ~.001 at 300 K and to ~.0001 at 225 K.

The data can be used for isotopologs 
with 13C or 18O substition with small errors 
with D with small to modest errors.

The fundamentals were taken from
Johnson, T. J., Sams, R. L., Profeta, L. T. M., et al., 2013, J. Phys. Chem. A, 117, 4096

The experimental values for the three lowest vibrations determined from high-resolution spectroscopy 
differ slightlyly in two cases and somewhat more in one case. The numbers have been reevaluated. 
However, the differences may well be smaller than those caused by the harmonic approximation.
