# Where can I find (citable) FTIR spectra of CuCl and CuCl2?

I can't seem to find any published/citable infrared (FTIR) spectra in the 4000-400 cm-1 range of CuCl and CuCl2. Does anyone know of a source available, either free or paid?

Beside the databases behind a paywall, freely accessible databases like the NIST webbook may be worth to consult; the entry about $\ce{CuCl2}$ here mentions in the references already one with IR data of gaseous $\ce{CuCl2}$ (here).
