Deuteration of Bronsted acidic sites in zeolites gives observable infrared in-plane O-D bending modes. For zeolite Y and ZK-5, a maximum near 870 cm-' with a shoulder near 890 cm-' is observed. These signals arc related to, respectively, the highfrequency and the low-frequency stretching modes. Mord
