Abstract
The IR spectroscopic study on pelletised barium hydrogen phosphate (BHP) has been made. The distinct bands observed seem to be related with the PO bond of PO 4 group. Around the ferroelectric transition at 315 K, the interionic band at 2650 cm −1 disappears on account of Ba⋯O ionic bond being broken. For the sample prepared at 500 K, the bands around 2000 and 2500 cm −1 appear intense, while broadening of bands due to various deformations like PO and PO–H takes place.
