# 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?

If your institution holds a subscription to Elsevier's database Reaxys, than you may find, based on chemical name, molecular formula, or CAS number (the later for example from a catalogue of a supplier of chemicals) links to primary literature in the section of spectroscopic properties. Reaxys tries to cover both organic materials (formerly deposited in the Beilstein database) and inorganic / metalorganic materials (formerly deposited in the Gmelin database). Otherwise, Scifinder from the ACS equally points towards primary literatures, too.

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).

• Thank you. But unfortunately I can't access those databases, only paid articles. :( The NIST webbook has entries for both, but CuCl (or ClCu as they put) has no references in it at all. I checked the article you mention (thanks), but it has no data in the 4000-400 cm-1 range (which is what I need, and I will edit the question now to state it, sorry). – R'A May 25 '17 at 15:08
