Abstract
It is shown that the coalescence of the nu(CO) infrared bands of trica rbonyl(eta(4)-norbornadiene)iron cannot be explained on an ''intrawell '' mechanism and must involve ''interwell'' dynamics. This leads to th e general conclusion that vibrational spectroscopic evidence for chemi cal exchange (i.e. ''interwell'') can be obtained by demonstrating tha t there is extra intensity between spectral bands that cannot be expla ined by simple overlap of individual bands.
