Abstract
The IR spectroscopic study on pelletised barium hydrogen phosphate (BHP) ha s been made. The distinct bands observed seem to be related with the P=O bo nd of PO4 group. Around the ferroelectric transition at 315 K, the interion ic band at 2650 cm(-1) disappears on account of Ba...O ionic bond being bro ken. 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 lik e P=O and P=O-H takes place.
