✦ Synopsis

The absorption of CO on variously treated samples of CuNa-Y zeolite has been studied. The number and position of the v(C0) bands is shown to be a function of the treatment conditions. This enables previously published results to be rationalized.

Bands at 2156,2142, and 2127 cm-' are due to Cu(l)-CC complexes in Sr or S;, S,;, and SII sites, respectively. An additional band at 2178 cm-' is assigned to CC interacting with a true Lewis acid site in autoreduced samples.
