We present in this Communication preliminary time-resolved fluorescence measurements of supersonaically cooled samples of pDFB and pFT. These measurements indicate that IVR in both cold molecules up to ~1600 cm^-1 of excess vibrational energy is substantially less than that reported for the same vibrational excitations in room temperature chemical timing studies.
