Vedclass · Answer

(B) $1$. Morphology of nanomaterial: $FTIR$ does not provide information about the morphology (shape,structure) of nanomaterials. Techniques like $SEM$ or $TEM$ are used for this.$2$. Absorption of functional group: $FTIR$ identifies functional groups by detecting characteristic absorption bands in the infrared region,such as those for $-OH$,$-CH$,$-NH$,and $-CO$ groups. This is the correct information collected by $FTIR$.$3$. Geometry of particles: $FTIR$ does not give information about particle geometry (e.g.,spherical or cubic shapes).$4$. Particle size: $FTIR$ cannot determine particle size. Techniques like $DLS$ (Dynamic Light Scattering) or electron microscopy are used for this.
