Abstract
Vibrational data of vapour, liquid and matrix-isolated fluorocarbonyl isocyanate, FC(O)NCO, were investigated. A subsequent normal coordinat e analysis was performed for the A' species of the predominant planar cis conformer (C=O double bond cis with respect to the vicinal N=C dou ble bond). The following internal force constants were derived: f(C=O) = 12.88 mdyn angstrom-1, f(C-F) = 6.20 mdyn angstrom-1 and F(C-N) = 4 .42 mdyn angstrom-1.
