摘要
We report the first vibrational sum frequency generation (VSFG) spectroscopic study from particle surfaces of powdered solids using a modified SFG approach, diffuse reflection broad bandwidth sum frequency generation (DR-BBSFG). The DR-BBSFG spectrum of sodium dodecyl sulfate (SDS, C12H25SO4Na) powdered solids was obtained. Five peaks were resolved by calculated fits. Possible origins of the SFG response from SDS particle surfaces are discussed. Potential applications of DR-BBSFG spectroscopy are addressed. Copyright © 2002 American Chemical Society.
