Acidity by IR Spectroscopy
{"Image DocumentName": "Acidity by IR Spectroscopy", "Image ImageDescription": "On heating ammoniated form hydroxyl groups are formed which display IR bands at. 3742,3643 &3540 cm-1 as shown in structures I & II- Bronsted acid sites. Beyond 450\u00baC, de-hydroxylation takes place resulting in Structure III leading to. Lewis acid sites, tri-co-ordinated Al - Lewis acid site.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
