Four structures shown in the figure reproduce the
experimental rotational constants equally well.
Structural parameters in structure 1 are reproduced
in the table.

) Uncertainties were not estimated in the
original paper.
b
) Hydrogen bond distance.
c
) Angle between the O…H bond and the
C−N−C plane, see figure.
