  A subset of the highly excited eigenstates of thiophosgene (SCCl$_{2}$) near
the dissociation threshold are analyzed using sensitive measures of quantum
ergodicity. We find several localized eigenstates, suggesting that the
intramolecular vibrational energy flow dynamics is nonstatistical even at such
high levels of excitations. The results are consistent with recent observations
of sharp spectral features in the stimulated emission spectra of SCCl$_{2}$
