摘要：

The absorption of CO on variously treated samples of CuNa-Y zeolite has been studied. The number and position of the v(CO) 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** minus **1 are due to Cu(I)-CO complexes in S//I or S prime //I, S prime //I//I, and S//I//I sites, respectively. An additional band at 2178 cm** minus **1 is assigned to CO interacting with a true Lewis acid site in autoreduced samples.
