Infra-red Spectroscopy of the Soil Humic Acids of the Sal (<I>Shorea robusta</I>) Forests of Doon Valley

Abstract

The soil humic acids from the sal forests of Doon Valley have been analysed under infra-red spectroscope for the identification of various functional and atomic groupings in them.The IR spectra do not indicate much difference in their structure and functional groups which are mainly carboxyl, phenolic and quinones.
